Dang, those are cool! Like Mesa esp32 boards! Alex can comment on compatibility- but these will be supported in the future if they aren’t already

There is documentation:

Question is will it work?

They are cheap too, the board cost me less then if I just bought all the connectors! https://aliexpress.com/item/1005003736312354.html
looks simple, will try in a few hours.
void setup() {
Serial.begin(115200);
delay(3000);
kc868.begin(115200);//open the kc868 first
kc868.setReadMode(0);//mode, 0 :default, Query directly; 1: Query all switch state every 2s
kc868.setSwitchChangeHook(SwitchUpdate);//set switch change hook
kc868.setSensorChangeHook(SensorUpdate);//set sensor change hook
Serial.println("Write Switch 1 on.");
kc868.writeSwitch(1,1);
int ret = kc868.readSwitch(1);
Serial.printf("The state of Switch 1 is %d .\n",ret);
Serial.println("Delay 1 second.");
delay(1000);
Serial.println("Write Switch 1 off.");
kc868.writeSwitch(1,0);
ret = kc868.readSwitch(1);
Serial.printf("The state of Switch 1 is %d .\n",ret);
}
oh wow they are cool indeed.
I guess once we know which Pin is which IO we could flash the Arduino firmware onto it easily.

It's not that easy.
The board uses pc8574's to get the large number of in and outputs. So we have to use the kc868.begin(115200);//open the kc868 first
driver. But that will work with an edit of your source code.
Or we could do it like this: https://www.kincony.com/forum/showthread.php?tid=1620
There is an API for the board if you use KC868 Arduino library:
