CANBed RP2040 is a CAN Bus development board equipped with an RP2040 chip with a high-performance MCP2515 CAN controller and MCP2551 CAN receiver operating at CAN2.0 protocols in 133MHz. The board contains a flexible CAN interface where it can be used 4-PIN Terminal or D89 connector. D89 connector can be directly used as OBD-II mode by default and the hardware can be configured as CAN Open mode as well. Additionally, it has a rich interface in which there is a Micro USB connector that can be programmed instead of supplying power. It also has I2C, UART, SPI, 3 analogue input interfaces, and 8 digital IO with 2MB of Flash and 264KB of RAM which make it suitable for the most embedded applications.

If you want to use this board to develop OBD related applications, click to get a DB9 to OBD-II cable.

We use a flexible way for the CAN interface. You can use 4PIN Terminal or DB9 connector. DB9 connector uses OBD-II mode by default. You can also configure CAN Open mode on the hardware. The voltage input range of the CAN interface is 9-28V, which can provide a stable 3.3V/1A output.
