Add a simple microphone to microcontroller or GPIO based projects





The kit integrates the ReSpeaker Lite dual-microphone array and a powerful pre-soldered XIAO ESP32S3 processor, offering exceptional voice recognition, noise reduction, and voice processing capabilities thanks to its onboard AI NLU algorithms.








For applications where you might want to use the USB output into a Pi!




An all-in-one module for easily sensing sound!



This small breakout board couples an Electret microphone (100Hz--10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontroller’s analog-to-digital converter.









Integrate a self-learning speech recognition module over I2C for hands-free voice control in microcontroller projects, from robotics to smart lighting.





Transform your projects with the ReSpeaker 2-Mic Voice Assistant Maker Kit, featuring dual microphone array technology, XMOS XU316 AI chip, and ESP32S3 integration for custom voice control applications and smart home automation, all bundled up in a neat package.

The Raspberry Pi Codec Zero is a Raspberry Pi Zero-sized audio I/O HAT. It delivers bi-directional digital audio signals (I2S) between Raspberry Pi Zero and its onboard Dialog Semiconductor DA7212 codec.
