Hi. My name is Sasha, and this is my first post here. I am in the planing fase for the truck to camper conversion. I would like to monitor and automate all sorts of things in the camper. Sensors are there, relays are out of the quesion, and I havent found MOSFET board that I like. What caught my attention is Infineons PROFET Smart High-Side Switch series. It is actually very robust logic-level MOSFET IC with all sorts of protections and diagnostics. One of it`s features I found very interesting is a current sense feedback. There are varous evaluation boards available, but most of them are arduino form factor. I got myself a Microelectronica PROFET CLICK - 15A to play with: PROFET Click - 15A After some playing with it, I liked it, so I have designed a custom DIN rail ready PCB containing 4 PROFETs. It looks like this…

I am not a coder and I am not using full diagnostics even the Infineon has provided a library. I am using ESPhome, and For now, I can just switch it on/off and measure the current with ADS1115. It would be amazing to have full diagnostics and some ESPHome template that can be adjusted to act as an electronic fuse. I will provide more details about the PCB when I get back home. Please comment and advise.
