Will it be possible to connect an ethernet PHY to the MicroMod board ?
Looking at the schematic for T4.1 the DP83826 uses B1_04 to B0_15 but that doesn't seems to be connected the the M.2 edge connector.
I can only see one CAN transceiver board. You need one transceiver for each CAN node.
You can't connect CAN_H and CAN_L to the Teensy like that. It need to go via a CAN transceiver.
