  • Adopts MCP2515 CAN Bus controller with SPI interface
  • OBD-II and CAN standard pinout selectable at the sub-D connector
  • Industrial standard 9 pin sub-D connector or 4PIN Terminal
  • Implements CAN V2.0B at up to 1 Mb/s
  • 18 pins that include digital pins, analog pins, UART, and I2C interface
  • Requires no other MCU to control
  • 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 an 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.

Application

  • Car hacking: The user can connect the circuit board to the OBD interface through the sub-D connector to read the data of the car
  • Easy building prototype: ATmega32U4 chip leads out various additional functions which help especially beginners build various prototypes.

Hardware Overview

1.9x2 IO Pin OUT: The IO of Atmega32U4 is listed out here

2.ATmega32U4 Chip:

The master of the entire module is 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.

A: Reset Button: Reset the on-board Atmega chip.

3. Micro USB connector for programming

4. ICSP Header for uploading bootloader

5. CAN RX/TX Indicator

6. sub-D connector or Terminal for CAN Bus

7. Switch for the 120Ω terminal resistor for CAN Bus

If you use this slaver at the end of the CAN bus, you need to solder a 120Ω resister between the two pads, if not just leave them alone. 

8. Grove connector for UART

9. Grove connector for I2C

    Product worked as described, sample code simple and good.
    Need to add LCD and Sensors, fairly sure it will work ok.
    Would be good to have a bit more information on examples and use of canbed with other add on products, might help your sales.
