Waveshare CAN Bus Module (B) for Raspberry Pi Pico, SPI Long-Range Communication

CAN bus is the backbone communication standard behind most vehicle electronics and a large share of industrial control systems, prized for its noise resistance and reliability over distances where a simpler serial link would start dropping data. This module brings that capability to the Raspberry Pi Pico over a straightforward SPI connection, opening up projects like vehicle diagnostics, industrial equipment monitoring, or any build that needs to talk to existing CAN-based hardware. The SPI interface keeps the Pico-side wiring simple despite the sophistication of what's happening on the CAN bus itself.
