KC868-A16 esp32 board (A16)as upgrade of a Homevision Controller?

[hjahend]

Received the A16 Controller board yesterday. It looks OK, but the shipment did not contain any documentation.
For proper testing and configuring the board with ESPHome, please provide me with the A16-board hardware <-> ESP32-GPIO pin relation specification:
a16 board input1,2,3 -> 16 = gpio x1, x2, x3 etc. to x16.
a16 board analogue inputs 1--->4 = gpio y1,y2,y3,y4;
a16 board I2C pins= gpios ….
a16 board Free gpios 1->3= …..
a16 board RF 433 MHz: pin tx gpio= gpio.. and rx= gpio …
a16 board Ethernet pin(s)= gpio ….
a16 board USB pins= gpio ...

Also needed advice: which ESPHome configuration file is best to start with for the a16 board?
thx in advance
