USB Type C for programming (CH340C for USB to UART).hardware also supports the upcoming Matter protocol (over WIFI).

So, if there is enough interest, I would think about ordering more than 5 and putting the PCB on - depends your feedback If you see any errors or possible pitfalls, please tell me or ask me why While drawing the schematics I tried to comment my design decisions. So there may be some mistakes in the schematics. I have a professional background in electrical engineering, but I mostly research FPGA at work. For controlling CAN-devices like heatpumps via ESPHome or Matter The design can be used for controlling / monitoring every / generic CAN-attached device.Ĭurrent state of development is here: GitHub - mkaiser/ESP32-CAN: PCB with ESP32 and CAN bus. While drawing the schematics, I realized, that the design is not limited to heatpumps.

I started to create a PCB to control my heatpump via CAN-bus, basically for this ESPHome project.Īfter seeing many posts regarding how to properly connect hardware (and of course doing this with jumper wires), I decided to go more public with my design - maybe it will help others.
