M5Stack ATOM Echo Smart Speaker Development Kit

The ATOM ECHO is a Programmable Smart Speaker based on the M5 ATOM design made popular due to its ability to be used as a low-cost Home Assistant voice assistant! Its form factor is very compact with dimensions of just 24 x 24 x 17mm. Music can be played using the Bluetooth capabilities of the ESP32 from a mobile phone or tablet. The device can be programmed to access AWS, Baidu and other cloud platforms, using the built-in microphone and speaker for voice interaction, offering AI capabilities, voice control, storytelling, Internet of Things and other project possibilities. The speaker is embedded with an RGB LED (SK6812), which can visually display the connection status. In addition to being used as a Bluetooth speaker, it has the control ability of the Atom series. The screw holes on the back are also convenient for users to fix to panels. Note: please avoid the following conditions with M5Stack Atom Echo:
