Did you install this in PDC module?
What CAN BUS transceiver are you using for D-CAN? Is TJA1050 or TJA1051 capable to read D-CAN? (As I know MCP2551 is not capable to read CAN BUS low speed)
I used an old PDC housing and PCB with all smd components stripped. It's a nice case and the board has nice TE automotive connectors.
I've gone through a few hardware revisions, the latest of which is based on Teensy 4.0. Expansion board is SK Pang triple can. The transceivers are MCP2561/2.
D-CAN is actually high-speed 500K. You're thinking of KCAN which is 100K and should be used with Fault Tolerant transceivers.
I really should update the OP as it's woefully out of date.
