CANBed FD - Arduino CAN-FD Development Kit
CAN Bus is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools, such as an automotive diagnostic bus.
This CANBed-FD adopts MCP2517FD CAN Bus controller with SPI interface and MCP2542FD CAN transceiver to achieve the CAN-BUS capability. With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device.
What's more, the is an Atmega32U4 with Arduino Leonardo bootloader on the board, you can use Arduino IDE to program the board easily.

The IO of Atmega32U4 is list out here.
The master of the entire module, mainly used to store data on the TF card or transfer data to the computer through the type C cable. In addition, since it's arduino compatible, you can use it to implement some simple controls, such as triggering a buzzer alarm when the speed exceeds a certain value.
Reset the on-board Atmega chip.
3.Micro USB connector for programming
4. ICSP Header for uploading bootloader
5.CAN RX/TX Indicator

7.Switch for the 120Ω terminal resistor for CAN Bus
If you use this slaver on the end of the CAN bus, you need to solder a 120Ω resister between the two pad, if not just leave them alone. For more detail about the CAN bus protocol, please refer to the NI CAN Physical Layer and Termination Guide
8.Grove connector for UART
9.Grove connector for I2C
IDE and Driver¶
There's Arduino leonardo bootloader in the board.
Click to get the latest Arduino IDE.
There's Arduino Leonardo driver in the folder: Arduino/drivers.
We provide an Arduino library for CANBed-FD.
Change the CS pin to 17.
There're many examples for the library, which is consist of,
- CAN_20_Send - How to send a frame to CAN Bus at CAN 2.0
- CAN_20_Recv - How to recv a frame from CAN Bus at CAN 2.0
- CAN_FD_Send - How to send a frame to CAN Bus at CAN-FD
- CAN_FD_Recv - How to recv a frame from CAN Bus at CAN-FD
