The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices.\u003c\/p\u003e\n\u003cp\u003eWhat really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.\u003c\/p\u003e\n\u003cp\u003eThe level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage (3.3V for example) to 'LV', and ground from the system to the 'GND' pin.\u003c\/p\u003e\n\u003cp\u003eGet Started with the Logic Level Converter Guide\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 0.63 x 0.52\" (16.05 x 13.33mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cdiv id=\"documents-tab\" class=\"tab-pane fade\" role=\"tabpanel\"\u003e\n\u003cdiv class=\"col-sm-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003e\nDatasheet (BSS138)\u003c\/li\u003e\n\u003cli\u003eHookup Guide\u003c\/li\u003e\n\u003cli\u003eGitHub\u003c\/li\u003e\n\u003cli\u003eProduct Video\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":43643623079997,"sku":"jzs1789691339066","price":4.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/sparkfun-logic-level-converter---bi-directional_1.jpg?v=1789691345"},{"product_id":"adafruit-mcp23017-i2c-gpio-expander-breakout-stemma-qt-qwiic","title":"Adafruit MCP23017 I2C GPIO Expander Breakout (STEMMA QT \/ Qwiic)","description":"\u003cp\u003eWe’ve gotten a lot of requests for a MCP23017 breakout and we’ve always sorta been like “ehh why not just use the DIP chip?” but with STEMMA QT we could see the use case for a plug and play version that comes with all the passives on board. This \u003cstrong\u003eAdafruit MCP23017 I2C GPIO Expander Breakout\u003c\/strong\u003e has 16 GPIO with matching ground pad.\u003c\/p\u003e\n\u003cp\u003eWe particularly like the '17 as an expander for it's simple no-nonsense capability. It runs happily from 3V or 5V logic and power. Each GPIO can be an output driving up to 25mA, so LEDs are no problem. Or, each can be an input, with optional pullup. There are two IRQ pins that are configurable for what inputs to keep track of so no I2C bus polling is required. With 3 address pins, you can have up to 8 on a single bus for a total of 8 x 16 = 128 GPIO all on one I2C bus!\u003c\/p\u003e\n\u003cp\u003eWe've got solid Arduino and CircuitPython libraries with examples, all ready for this chip. But even if you are using some other platform, the MCP23017 is so classic, you'll likely be able to find example code.\u003c\/p\u003e\n\u003cp\u003eComes with two sticks of header so you can use it in a breadboard, with some soldering. You can also free-wire buttons by connecting one side to the GPIO (set as input with pullup) and the other side to a ground pad.\u003c\/p\u003e\n\u003cp\u003eTo get you going fast, we spun up a custom-made PCB in the \u003cstrong\u003eSTEMMA QT\u003c\/strong\u003e form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors.

The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L4CD can detect the \"time of flight\", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53 is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.\u003c\/p\u003e \u003cp\u003eThis is another 'big sister' of the VL6180X ToF sensor and can handle about ~1 to 1300mm of range distance: basically it combines the short range of the VL6180X in that it can sense up to the body of the sensor, with the increased range of the VL53L0X, which can handle about 50mm to 1200mm of range distance.\u003c\/p\u003e \u003cp\u003eThe sensor is small and easy to use in any robotics or interactive project. Since it needs 2.8V power and logic we put the little fellow on a breakout board with a regulator and level shifting. You can use it with any 3-5V power or logic microcontroller with no worries. Works great with the \u003cstrong\u003e3.3V logic level of a Feather or Raspberry Pi, or the 5v level of a Metro 328 or Arduino Uno\u003c\/strong\u003e, this breakout is ready to work with most common microcontrollers or SBCs. and since it speaks I2C, you can easily connect it up with two data wires plus power and ground. \u003c\/p\u003e \u003cp\u003eAs if that weren't enough, we've also added SparkFun qwiic compatible \u003cstrong\u003eSTEMMA QT\u003c\/strong\u003e connectors for the I2C bus \u003cstrong\u003eso you don't even need to solder.\u003c\/strong\u003e Just wire up to your favorite micro with a plug-and-play cable to get ToF data ASAP. For a no-solder experience, just wire up to your favorite micro, like the STM32F405 Feather using a STEMMA QT adapter cable.

On the other hand, this little board has good performance in processing but requires less power.

Some pins have various functions, A1\/D1 to A10\/D10 have PWM functions and A0\/D0 has a DAC function which means you can get true analog signals (not PWM signals) when you define it as an analog pin, that’s why 14 GPIO pins can offer more I\/O and interfaces.\u003c\/p\u003e\n\u003cp\u003eMoreover, the Seeeduino XIAO supports the \u003cstrong\u003eUSB Type-C\u003c\/strong\u003e interface which can supply power and download code.

And his very favourite is whenever folks first start with electronics and robotics: wiring up a motor or solenoid or high power LED is a perfect recipe for getting that blue smoke out of an Arduino or Raspberry Pi. Why? Because these high-current devices can't be connected directly to a GPIO pin on a microcontroller! They need to have a transistor \/ MOSFET driver, plus a kickback-protection diode that will absorb the inductive 'kick' caused by turning on-and-off motors and solenoids. Without that driver and diode - your tronix will go poof!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: The connector is not STEMMA QT!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWe have tutorials on how to wire up the components to create a transistor driver on a breadboard, but it's easy to put the diode in backwards, or pick the wrong kind of transistor. And some folks don't want to have the extra breadboard for just controlling a simple motor fan or solenoid. This is why we designed the Adafruit STEMMA MOSFET Driver for Motors, Solenoids, and LEDs.\u003c\/p\u003e\n\u003cp\u003eThis board has a simple plug-and-play JST PH (2mm pitch) input connector for solderless use. Provide power (from 3V up to 30V) and signal (3V to 20V logic level). On the output are two-output terminal blocks, with one block connected to power and the other switched to ground when the signal level is high. In between is an AO3406 N-Channel MOSFET rated for 30Vds, 3.6A peak, and 70mΩ RdsOn plus a 1N4007 flyback diode.\u003c\/p\u003e\n\u003cp\u003eYou can also get to all the signal and power pins on a 0.1\" breakout header if desired, but we expect most folks will like using it as a solderless MOSFET-buddy. Great for driving motors, inductors, high power LEDs, single-colour LED strips, or other loads up with to 1.5 Amps continuous draw, 3 Amp peak. Note that the JST PH connector itself is only rated for 2 Amp continuous.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/LozkVvwtsa0?start=265\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eProduct Dimensions: 25.4mm x 17.7mm x 7.2mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProduct Weight: 2.4g \/ 0.1oz\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003eResources\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003ePrimary Guide: Adafruit MOSFET Driver\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43643767619645,"sku":"lqr1789694082263","price":3.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/adafruit-mosfet-driver---for-motors-solenoids-leds-etc---stemma-jst-ph-2mm_1.jpg?v=1789694087"},{"product_id":"seeed-xiao-esp32c3","title":"Seeed XIAO ESP32C3","description":"\u003cp\u003eThe Seeed XIAO ESP32C3 has a highly-integrated ESP32-C3 chip, built around a 32-bit RISC-V chip processor with a four-stage pipeline that operates at up to 160 MHz.\u003c\/p\u003e\n\u003cp\u003eThe board equips highly-integrated ESP32-C3 SoC.

Owing to the high permeability and the small volume between the sensing element and membrane, the specified response time of the RH sensor is unaltered.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAccuracy Specification: ΔRH = ±1.0 %RH, ΔT = ±0.1 °C\u003c\/li\u003e\n\u003cli\u003eBreakout board Vdd\/logic: 3.3V to 5V\u003c\/li\u003e\n\u003cli\u003eAvg. current: 0.4 µA, Idle current: 80 nA (not including on-board regulator quiescent)\u003c\/li\u003e\n\u003cli\u003eI2C FM+, CRC checksum, default I2C addr 0x44\u003c\/li\u003e\n\u003cli\u003eOperating range: 0 … 100 %RH, −40…125 °C\u003c\/li\u003e\n\u003cli\u003eFully functional in a condensing environment\u003c\/li\u003e\n\u003cli\u003ePower heater, true NIST-traceability\u003c\/li\u003e\n\u003cli\u003eJEDEC JESD47 qualification\u003c\/li\u003e\n\u003cli\u003eSensor-specific calibration certificate acc. to ISO 17025: 2017, 3-point temp. calibration\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDimensions: 25.5mm x 17.7mm x 4.8mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWeight: 1.7g\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePrimary Guide\u003c\/li\u003e\n\u003cli\u003eSHT4x Datasheet\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Without PTFE","offer_id":43643770798141,"sku":"nix1789694296296","price":11.97,"currency_code":"USD","in_stock":true},{"title":"With PTFE","offer_id":43643770830909,"sku":"tbo1789694296297","price":13.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/adafruit-sensirion-sht45-precision-temperature-humidity-sensor---stemma-qt-qwiic_1.jpg?v=1789694301"},{"product_id":"rgb-full-colour-led-matrix-panel-4mm-pitch-64x32-pixels","title":"RGB Full-Colour LED Matrix Panel - 4mm Pitch, 64x32 Pixels","description":"\u003cp\u003eCreate your own colourful displays with text, shapes and sequences with this \u003cstrong\u003e64x32\u003c\/strong\u003e \u003cstrong\u003e4mm pitch\u003c\/strong\u003e RGB LED Matrix panel from Waveshare.\u003c\/p\u003e\n\u003cp\u003eThis LED matrix panel contains \u003cstrong\u003e2048 individual RGB LEDs\u003c\/strong\u003e which you can control with your favourite compatible microcontroller.

Note that not all chips have a CAN peripheral! Some that we know do have it are the ESP32\/ESP32-S2\/ESP32-S3 (note that ESP32 calls this interface TWAI not CAN) series of chips, SAME51, STM32F405, or Teensy 4.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNOTE\u003c\/strong\u003e: Check the product documentation for the board you are wiring this to, to make sure that the chip has CAN support and the RX and TX pins are brought out for you to connect the transceiver to!

New nodes can be attached easily because they just need to connect to the two data lines anywhere in the shared net. Each CAN device sends messages whenever it wants, and thanks to some clever data encoding, can detect if there's a message collision and retransmit later.\u003c\/p\u003e \u003cp\u003eWe've added a few nice extras to this breakout pal to make it useful in many common CAN scenarios:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\nTJA1051\/T3 can communicate with 3.3V~5V logic for use with modern microcontrollers.\u003c\/li\u003e \u003cli\u003e\n5V charge-pump voltage generator, so even though you are running 3.3V power and logic on most modern microcontroller boards, it will generate a nice clean 5V as required by the transceiver.

Two is more than one, so that makes it twice as good! And the Adafruit Feather RP2040 with USB Host is definitely double the fun of our other Feather RP2040 boards, with a USB Type-A port on the end for connecting USB devices to.\u003c\/p\u003e\n\u003cp\u003eNow you might be thinking \"Hey wait a minute, the RP2040 doesn't have two USB port peripherals?\" and you'd be correct! But what it does have is a nifty PIO peripheral that can be (ab)used to emulate a USB host peripheral. You get to keep the main USB port for uploading, debugging, and data communication, while at the same time sending and receiving data to just-about-any USB device. This work is originally done by Sekigon on GitHub, and if you're using Pico SDK that's still the recommended library to use.\u003c\/p\u003e\n\u003cp\u003eCurrently, support for the USB Host peripheral is only in Arduino. So check out the TinyUSB 'dual role' examples for some things you can do! For example, data logging to a USB Key. Or reading from another device\/microcontroller that has USB CDC serial interface. Or creating an HID re-mapper. Or connecting to weird devices that require firmware updates like the Cypress EZ-USB-based Intellikeys communications board.\u003c\/p\u003e\n\u003cp\u003eNote that this is definitely a firmware hack: you will need to dedicate the second ARM core and both PIO peripherals to just handling the USB messages, but we find that it does work fairly well, or at least as well as most microcontroller's USB Host peripherals!\u003c\/p\u003e\n\u003cp\u003eWe also include a 1 Amp boost converter based on the TPS61023 so you can run from a Lipo battery and get a nice clean 5V output for the USB devices. The booster has the enable pin tied to one of the extra GPIO on the RP2040 so power can be manually turned on and off to hard-reset whatever is connected.\u003c\/p\u003e\n\u003cp\u003eAt the Feather's heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8MB of onboard QSPI FLASH and 264K of RAM! There's even room left over for a STEMMA QT connector for plug-and-play of I2C devices!\u003c\/p\u003e\n\u003cp\u003eTo make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the USB Type C connector. But, if you do have a battery, you can take it on the go, and then plug in the USB to recharge. The Feather will automatically switch over to USB power when it's available.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/WxLDsQwKVpY?start=176\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures 2.0\" x 0.9\" x 0.28\" (50.8mm x 22.8mm x 7mm) without headers soldered in\u003c\/li\u003e\n\u003cli\u003eLight as a (large?) feather - 6.3 grams\u003c\/li\u003e\n\u003cli\u003eRP2040 32-bit Cortex M0+ dual core running at ~133 MHz @ 3.3V logic and power\u003c\/li\u003e\n\u003cli\u003e264 KB RAM\u003c\/li\u003e\n\u003cli\u003e8 MB SPI FLASH chip for storing files and CircuitPython\/MicroPython code storage.

It's basically our ESP32-S3 TFT Feather but with the 240x135 colour TFT display on the back side, not the front side. That makes it great for panel-mounted projects, particularly since we've also got some space for 3 buttons to go along. It's like an all-in-one display interface dev board, powered by the fantastic ESP32-S3 WiFi module.\u003c\/p\u003e\n\u003cp\u003eThis Feather comes with native USB and 4 MB Flash + 2 MB of PSRAM, so it is perfect for use with CircuitPython or Arduino with low-cost WiFi. Native USB means it can act like a keyboard or a disk drive. WiFi means it's awesome for IoT projects. And Feather means it works with the large community of Feather Wings for expandability.\u003c\/p\u003e\n\u003cp\u003eThe ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi\/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.\u003c\/p\u003e\n\u003cp\u003eThe Feather ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32's dual-core. However, there is no Bluetooth Classic support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module we are using on the Feather comes with 4 MB flash and 2 MB PSRAM, as well as lots of 512KB of SRAM so it's perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It's also great for use in ESP-IDF or with Arduino support.\u003c\/p\u003e\n\u003cp\u003eThe colour TFT is connected to the SPI pins and uses additional pins for control that are not exposed to the breakout pads. It's the same display as you see here, with 240x135 pixels and is IPS so you get bright colours at any angle. The backlight is also connected to a separate pin so you can PWM the backlight up and down as desired.\u003c\/p\u003e\n\u003cp\u003eFor low power usage, the Feather has a second low-dropout 3.3V regulator. The regulator is controlled with a GPIO pin on the enable line and can shut off power to the Stemma QT port and TFT.
