Configuration for ESP32
{"NAME":"KC868-A4","GPIO":[32,0,227,0,224,225,0,0,0,1312,1,226,0,0,480,1152,0,1120,1056,1088,0,1,1,1,0,0,0,0,4706,4707,4704,4705,1,0,0,1],"FLAG":0,"BASE":1}

Use the mini USB port to flash the device.

Terminals marked DA1 and DA2 are DAC GPIO’s 25 and 26 which can be controlled using Berry gpio.dac_voltage.

Digital inputs are optocoupler isolated. RF433 receiver and transmitter come only in some bundles.

Button marked S2 is a bit fussy when trying to use multi-press, adjust if needed using ButtonDebounce.
