Comparing a UART link with a CAN link for two boards a metre apart inside one enclosure, the UART is
Answer: C
Correct answer: adequate and much cheaper, needing no transceiver
Over a metre inside one enclosure a plain UART works directly between two microcontroller pins with no transceiver, no termination and no protocol controller. CAN’s differential signalling, arbitration and error handling exist for long, noisy, multi-node buses, and none of that is needed here. The UART does detect errors, through parity and framing, and a metre is far within its range.
