From: Chris Morgan <macromorgan@xxxxxxxxxxx>
The Powkiddy RGB20SX is a portable game console extremely similar to
the existing RGB30 console. The key differences from the RGB30 are
as follows:
- Realtek RTW8723DS WiFi and Bluetooth.
- UART pads for debug console (UART2).
- A function button (ADC channel 0).
- A much larger battery (5000 mAh).
Otherwise, the device is identical to the RGB30, including the
hard-coded value on ADC channel 1 used to identify the device at
runtime.
