Atom Echo is a programmable smart speaker based on the M5ATOM design ESP32. Its form factor is very compact, with dimensions of just 24 x 24 x 17 mm. Music can be played via 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. The built-in microphone and speaker enable voice interactions, giving the M5AtomECHO certain AI capabilities and allowing for simple voice control. The speaker is equipped with an RGB LED (SK6812) that visually indicates the connection status. It is not only used as a Bluetooth speaker but also offers the control capabilities of the Atom series. Additionally, sensors can be connected via the Grove interface. G21/G25 can only be used for general I/O and do not support I2C and UART.
