CANBed FD - Arduino CAN FD Dev Kit

Availability: In stock
The CANBed FD utilizes the MCP2517FD CAN Bus controller with SPI interface and MCP2542FD CAN transceiver to provide CAN Bus capabilities.

CANBed FD is a development board with an Atmega32U4 microcontroller with 32KB of Flash memory and 2.5KB of RAM. It operates at a frequency of 16MHz and comes with an Arduino Leonardo bootloader, which makes it easy to program using the Arduino Integrated Development Environment (IDE). Alternatively, you can use AVR Studio for development, as the board has an ICSP interface.

CANBed FD uses the MCP2517FD as its CAN controller and the MCP2542 (MCP2557) as its CAN receiver. These chips are high-performance and capable of working with both CAN 2.0 and CAN FD protocols. The board has a micro USB connector for programming and power supply, as well as I2C, UART, and SPI interfaces, 3 analog input interfaces, and 8 digital IO pins.

The CAN interface on CANBed FD is flexible, allowing you to choose between using a 4-pin terminal or a DB9 connector. By default, the DB9 connector uses OBD-II mode, but you can also configure it to use CAN Open mode through hardware. The input voltage range for the CAN interface is 9-28V, and it provides a stable 5V/1A output.

This CAN-Bus development board is fully compatible with the Arduino IDE. The Arduino CAN FD library helps to save time on your CAN project.
