Configuration for ESP32
{"NAME":"ESP32_Relay_X8","GPIO":[0,0,0,0,0,0,0,0,225,224,226,0,0,0,0,0,0,0,0,0,0,229,228,227,0,0,0,0,231,230,0,0,0,0,0,0],"FLAG":0,"BASE":1}Just solder some headers to the board and flash using serial, the only thing special is that you will power it using 5v while flashing.
