(I have been busy earlier this year so there was delay for my OBDuino project)
I am working on a PCB, I already made a prototype but I am reworking it to be less than 5cm height so it will fit easily in a 1 DIN unit.
There is some pictures here

Note that this is a CAN version only. While I was working on it, I am happy to see some people enhanced the ISO version a lot!
