I want to create my own CAN/LIN board for the Teensy3.6. (Using MCP2004 and MCP2551, because I have access to these transceivers)
I am trying to make the board with 2 CAN channels and 2 LIN channels (and I want to have access to all the other Teensy pins as well).
This is the complete schematics:
I have a couple of questions here that I hope you guys can help me with:
(also please know that I am not a hardware designer so the questions might be stupid)

- Should I be connecting the transceivers VCC-pin to the Teensy VIN (3.6-6 Volt) or to the Teensy 3.3 Volt? (I think I should be using the 3.3Volt but can it support enough current for all the 4 transceivers)?
- for the CAN transivers, should I connect RXD to Teensy CANxRX (and TXD to Teensy CANxTX) or is it the other way around? Aka TX to RX and RX to TD? I seem to always get this wrong?
