PRODUCT DETAILS
Note
We have already released CAN-BUS Shield V2 which is an Arduino shield based on CAN-BUS. This CANBed - Arduino CAN-BUS Development Kit carries an Arduino chip - Atmega32U4, which means it combines the CAN-BUS Shield and Arduino Development Board together on one single board.
Tip
We also prepared a blog Introduction to CAN BUS and How to use it with Arduino to help you learn more about CAN BUS and what projects you can start now.
Key Features
- ATmega32U4 with Arduino Leonardo bootloader on the board
- MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver
- OBD-II and CAN standard pinout selectable at the sub-D connector
- Compatible with Arduino IDE
Description
CANBed - Arduino CAN-BUS Development Kit embeds an ATmega32U4 chip, which means you don’t need to add other jump wires to another Arduino Board, it is an Arduino board itself plus MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver!
CAN-BUS is a common protocol and widely used in industry due to its long travel distance, medium communication speed, and high reliability. Now you can realize a CAN-BUS project through this tiny little development board.
Because of the ATmega32U4 onboard chip, this board has rich resources in pins. As a matter of fact, there are 18 pins based on core chip set up on the board, which include digital pins, analog pins, UART, and I2C interface. Besides, this CANBed adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 to achieve the CAN-Bus capability. There are also two kinds of CAN Bus interfaces for various demands which are sub-D9 connector and terminal block interface. They would fit all your needs in the connecting method.
This CAN-Bus development board is perfectly compatible with Arduino IDE. With the help of the Arduino CAN-Bus library, you will save plenty of time for your CAN project.

The IO of Atmega32U4 is listed out here
2.ATmega32U4:
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.
