Waveshare CAN Bus Module for Raspberry Pi Pico, UART to CAN Conversion

Where the SPI-based CAN module suits a project already comfortable wiring and driving an SPI peripheral, this version simplifies things further by presenting CAN bus access over plain UART - about as straightforward a serial interface as exists, with the module itself handling the UART-to-CAN protocol translation internally. That makes CAN bus connectivity accessible to a Pico project without needing a dedicated SPI CAN controller library, at the cost of some of the raw throughput an SPI connection can offer. A practical choice when simplicity of integration matters more than squeezing out maximum CAN bus bandwidth.
