Description

CANBed FD is a CAN FD dev board with an Atmega32U4 microcontroller inside, which has 32KB of Flash and 2.5KB of RAM. The operating frequency is 16MHz, which can meet most embedded applications. There's an Arduino Leonardo bootloader inside the Atmega32U4. If you have used the Arduino IDE, programming will not be a problem for you. 

CANBed FD uses MCP2517FD as CAN controller and MCP2542 (MCP2557) as CAN receiver, which is high-performance CAN Bus chips, that can work in both CAN 2.0 and CAN FD protocols at the same time. There is a Micro USB connector on the board, through which you can program the board or supply power to the board. There is one I2C, one UART, one SPI interface, 3 analog input interfaces, and 8 digital IO on the board.

This CANBed-FD Arduino CAN-FD Development Kit 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.

What are CAN Bus and CAN FD?

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.

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 of the original CAN bus protocol.
