Card based on ESP32 microcontroller.
This board was designed to drive 9 low power relays to control Yokis MVR500E rolling shutter automation.
As well as 8 zones (pilot wires) for heating.
It is possible to program the card via the planned PROG connector or by OTA (depending on the code)
Code under development (I accept help) a github will be set up soon

- Display connector
- Double imprint for power supply via BAT + and BAT- terminals
- Polarized relay wired upside down
- Miss track on pilot wire feed
