MCP2551 and MCP2515 Serial CAN-BUS Module enable your Arduino and other MCU to communicate to CAN-BUS to hack 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 MCP2551 and MCP2515, which provides speed up to 1Mb/s. It also has a terminal block so you can connect to your vehicle’s OBD-II port with two wires.

Size and Hardware Overview

• 4 pin 2.0mm Grove Connector
• Power and status led indicator
• Send and Recv led indicator
• 3.5mm terminal to connect to CAN-Bus (CAN_H & CAN_L)
• 120Ω resistor, default connected, if you don't need you cut this pad with a box cutter.

Features

• Cart to CAN-BUS communication
• Support AT command
• Up to 115200 UART baud rate (default 9600)
• Up to 1Mb/s CAN-BUS baud rate
• TX and RX led indicator
• 4pin Grove connector to plug and play
• 3.3V working voltage
• Easy-to-use Arduino library

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 baud rate.

Part List

• 1 x Serial CAN-Bus PCBA
• 1 x 4 Pin Grove cable
• 1 x Small screwdriver
