CANBed Dual is a CAN Bus development board with 2 independent CAN FD interfaces based on RP2040. It uses GD32E103CBT6 as the CAN controller with an operating frequency is up to 133MHz, which is suitable for most embedded applications.
You can use Arduino IDE to program the board easily.
CAN FD (Controller Area Network Flexible Data-Rate) is a data-communication protocol typically used for broadcasting sensor data and control information on 2 wire interconnections between different parts of electronic instrumentation and control system. This protocol is used in modern high performance vehicles. CAN FD is an extension to the original CAN bus protocol.
