Docs about the Node Module designed by M5Stack

DESCRIPTION

The Node is a sound box module with 12 RGBLed(SK6812), a codec chip(WM8978), DHT12, IR Transmitter and Receiver(CHQ0038H), two MICs. WM8978 is often used to be applied for Hi-Fi Speaker. You can program it after connected to any series of M5Stack Core through Arduino.

You can creat a Webradio, Bluetooth Speaker, even Intelligent sound box with this module.

For verifying the hardware, you can burn these example codes to Node.
