Adafruit RP2040 CAN Bus Feather with MCP2515 CAN Controller - STEMMA QT

The Adafruit RP2040 CAN Bus Feather combines a powerful Raspberry Pi RP2040 microcontroller with an integrated MCP25625 CAN controller and transceiver, providing ready-to-use CAN Bus connectivity without additional hardware. A pre-soldered terminal block offers convenient access to CAN High, CAN Low and Ground connections.

CAN Bus is widely used in automotive, industrial, robotics and distributed sensor network applications thanks to its reliability, long cable distances and noise immunity. The onboard MCP25625 supports both standard and extended CAN frames at speeds up to 1 Mbps.

In addition to CAN functionality, the board features a dual-core RP2040 processor, 8MB flash storage, battery charging circuitry, USB-C connectivity and a STEMMA QT connector for easy expansion with I2C sensors and accessories.
