The left side of the board exposes duplicate power pins, along with two additional signal lines (DAT1 and DAT2) that are not needed for SPI communication but are used in 4-bit SD bus mode. The DAT1 pin also serves as an interrupt pin (\u003cspan\u003eIRQ\u003c\/span\u003e) in SDIO devices. (Note that if you are using this module in a breadboard, you might want to solder header pins into both sides of the board for added stability even if you only plan to use the SPI pins.)\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/sd_pinout.jpg?v=1645720968\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe following tables describe the function of each pin on the breakout board in SPI and SD mode:\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/table0967.jpg?v=1645720722\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp class=\"note_warning\"\u003e\u003cstrong\u003eWarning:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eStandard microSD cards use 3.3V logic level signals, so level shifters or voltage dividers are required when connecting one to a 5V system.\u003c\/p\u003e\n\u003ch3\u003eCommunicating with a microSD card\u003c\/h3\u003e\n\u003cp\u003eThe SD Association publishes a set of\u003cspan\u003e \u003c\/span\u003esimplified specifications\u003cspan\u003e \u003c\/span\u003efor SD cards containing information on interfacing with them.

The CP2102N has better driver support than the CH340 and can do very high speeds, and variable speeds without stability issues.

The 6th pin is RTS, the power wire is +5V and the signal levels are 3.3V (they are 5V compliant, and should work in the vast majority of 3.3V and 5V signal systems). Works excellently with any Arduino, ESP8266, ESP32 or any other microcontroller that uses an 'FTDI port' for communications and upload. You can also purchase a 6-pin extension cable from us, which will let you rearrange the wire order.\u003c\/p\u003e\n\u003cp\u003eThere's also a full collection of all the modem control pins you may need on the side, in case you need the DTR, RI, DSR, etc. pins.\u003c\/p\u003e\n\u003cp\u003eEach order comes with a fully assembled and tested board.

It can do up to 10 location updates a second for high speed, high sensitivity logging, or tracking. Power usage is incredibly low, only ~29 mA during navigation.\u003cbr\u003e\u003cbr\u003eBest of all, we added all the extra goodies you could ever want: an ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs, ENABLE pin so you can turn off the module using any microcontroller pin or switch, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts and a tiny bright red LED. The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on.\u003cbr\u003e\u003cbr\u003eTwo features that really stand out about the MTK3333-based module are the external antenna functionality and the built-in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dBm sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector.
