CANBed RP2040 – CAN-Bus Development Board

The CANBed RP2040 is a CAN Bus development board with an RP2040 chip, a high-performance MCP2515 CAN controller and an MCP2551 CAN receiver that operates on CAN 2.0 protocols at 133 MHz. The board has a CAN interface, supporting either a 4-pin terminal or a D89 connector. The D89 connector is set to function in OBD-II mode by default but can also be configured for CAN Open mode.

In addition, it includes a Micro USB connector that can be used for programming and as a power supply. The board is equipped with I2C, UART, SPI, three analogue input interfaces, and eight digital I/O pins. With 2 MB of Flash memory and 264 KB of RAM, it is well-suited for a wide range of projects!
