Bad things happened

A project log for PelletMon - IoT for central heating / boiler.

Monitor pellet boiler status via CAN bus, measure fuel usage - RE + engineering = profit !

It looks like with 120 ohm resistor, I have introduced excessive termination that led to errors in CAN transmissions. I had to unsolder termination resistor from my board and trim my cables to work properly as CAN stub.

Enclosure arrived today, so I have mounted everything inside.

It requires more testing this time, but I hope that issue is fixed.
