Description

A ESP32 ad-on board/shield for controlling multiple IO's

Digital inputs via 1-Wire connexion

4 relay outputs, 5 mosfet outputs (12/24V).

I personal use it to control central heating and warm water production using a single mid temperature (55°C) heatpump. Arduino code generated by Jeeduino plugin in Jeedom home automation system.
