基於MCP2551和MCP2515的串行CAN總線模塊

This Serial CAN-BUS provides your Arduino or others MCU with the capability to communication to CAN-BUS, such as hacking your vehicle. CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. This Serial CAN-BUS module is based on MCP2551andMCP2515, which can provide speed up to 1Mb/s. There's Grove connect as well as Grove cable included in the kit, which allows connect the module to your Arduino easily, click to get more about Seeed Grove System.

• Small size

Size and Hardware Overview

1. 4 pin 2.0mm Grove Connector

2. Power and status led indicator

3. Send and Recv led indicator

4. 3.5mm terminal to connect to CAN Bus (CAN_H & CAN_L)

5. 120Ω registor, default connected, if you don't need you cut this pad with a box cutter.

OBD-II CAN-BUS Development Kit

If you want to hack your vehicle with this module, you can try OBD-II CAN-BUS Development Kit, which is consist of Serial CAN Bus module as well as OBD-II connector. 

Note: 

As the module uses serial communication, so the frequency of receiving data can't be too fast, you can receive a frame every millisecond under 115200 baudrate.
