NOTE: G19 / G22 / G23 / G33 has been defined, please do not reuse the above pins, otherwise ATOM ECHO will be damaged!!!
[ Play Music ] - Music can be played using the bluetooth capabilities of the ESP32 from a mobile phone or tablet. Note: please avoid such conditions with M5Stack Atom Echo: 1. DC output from I2S channel; 2.Playing white noise for a long time; 3. Playing full square-wave audio
[ Voice Interaction ] - The device could be programmed to access AWS, Baidu and other cloud platforms, using the built-in microphone and speaker for voice interaction, so that ATOM ECHO has certain AI capabilities, realizing voice control, story telling, Internet of things and other functions.
[ RGB LED Status Display] - 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 still has the control ability of Atom series.
[ Pin Definition ] - You can connect devices through the grove interface, G21 / G25 can only be used for general I/O, they do not support I2C and UART.
