{"product_id":"m5stack-atomic-voice-base","title":"M5Stack Atomic Voice Base","description":"\u003cp\u003eThis Atomic Voice Base (previously Echo Base) is a voice recognition module made for the M5 Atom series and has audio input and output capabilities. It combines an ES8311 mono audio decoder, a MEMS microphone, and an NS4150B power amplifier to give a great audio experience.\u003c\/p\u003e\n\u003cp\u003eThe ES8311 supports 24-bit audio resolution and operates at sample rates from 16KHz to 64KHz, using I2S communication for level audio processing. The MEMS microphone provides a high signal-to-noise ratio (SNR), making it ideal for speech recognition. Paired with a built-in speaker, you can hear your voice with a clear sound output.\u003c\/p\u003e\n\u003cp\u003eWith full-duplex communication, the Voice Base can handle voice input and output simultaneously. This makes it well-suited for tasks like voice commands, speech recognition, wake-up functions, and real-time audio playback.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with the M5 Atom series\u003c\/li\u003e\n\u003cli\u003eVoice recognition\u003c\/li\u003e\n\u003cli\u003eMono audio codec\u003c\/li\u003e\n\u003cli\u003eMEMS microphone\u003c\/li\u003e\n\u003cli\u003eClass-D amplifier\u003c\/li\u003e\n\u003cli\u003eSpeaker\u003c\/li\u003e\n\u003cli\u003eDevelopment platform\n\u003cul\u003e\n\u003cli\u003eUIFlow 1.0\u003c\/li\u003e\n\u003cli\u003eUIFlow 2.0\u003c\/li\u003e\n\u003cli\u003eArduino IDE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"587\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"228\"\u003eAudio Codec\u003c\/td\u003e\n\u003ctd width=\"359\"\u003eES8311: 24-bit resolution, I2S protocol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMEMS Microphone\u003c\/td\u003e\n\u003ctd\u003eMSM381A3729H9BPC, SNR ≥ 65 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Amplifier\u003c\/td\u003e\n\u003ctd\u003eNS4150B: Class-D power amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker\u003c\/td\u003e\n\u003ctd\u003e2014-type cavity speaker: 1W@8Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003eDC3.3V\/3.36mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Current\u003c\/td\u003e\n\u003ctd\u003eDC3.3V\/14.84mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 - 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e24.0 x 24.0 x 14.14mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e6.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging Size\u003c\/td\u003e\n\u003ctd\u003e85.0 x 65.5 x 15.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging Weight\u003c\/td\u003e\n\u003ctd\u003e12.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Wiki\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Atomic Voice Base\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":43643912618045,"sku":"wfw1789699007093","price":5.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/m5stack-atomic-voice-base_1.jpg?v=1789699011","url":"https:\/\/laser-engraved-clasp.shop\/products\/m5stack-atomic-voice-base","provider":"My Store","version":"1.0","type":"link"}
