M5Stack C008-C Atom Echo Development Tool

M5Stack C008-C Atom Echo Development Tool is a programmable smart speaker based on the M5ATOM design. The C008-C atom echo development tool plays music using bluetooth capabilities of the ESP32 from a mobile phone or tablet. This tool could be programmed to access AWS, Baidu, and other cloud platforms, using the built-in microphone and speaker for voice interaction. The C008-C atom echo should avoid playing white noise for a long time and full square-wave audio. This development tool comes with a very small form factor and its dimensions are 24mm x 24mm x 17mm.

The C008-C atom echo features a built-in microphone and speaker, RGB LED status display indication, GROVE extension interface, record and playback, and programmable key. This development tool is suitable for Bluetooth® speakers, voice control, and IoT applications.
