Description

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 MCP2551 and MCP2515, 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.

  • Up to 1Mb/s CAN-BUS baud rate

  • TX and RX led indicator

  • 4pin Grove connector

  • 3.3V working voltage

  • Easy-to-use Arduino library

  • 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.

I got one of these and there is no assembly instructions, no how to section available at longan site, the github repository seems pretty basic and does not provides a full example how to fetch data from the device. Hope have a 'professional' documentation soon related to this product cause looks promising.

I intend to use this module like a bidirectional RS 232 to CAN converter, using a UART to RS232 level shifter. RS 232 end will connect to a device and CAN to a PCI card on my PC. Will this work? If yes, how do I set baud rates, termination, etc. for the serial and CAN?

Thanks for the reply. How/where do I type in these AT commands? The RS 232 end device doesn`t have any way to access the processor. The CAN side is a PC, where I can do stuff but I am not sure if AT commands work over CAN. Can I use an Arduino UNO/Mega over UART or some hyperterminal over UART to set the configuration (baudrates, frame length, etc) once, and then just disconnect it from Arduino/Hyperterminal and use it as a converter with a non-smart device on one side and a PC on the other. Will these settings go back to default if I switch off and on the device?

Can I use it with Arduino Nano or Uno to monitor/write to GMLAN (SW-CAN)?

Put CAN-L to ground and CAN-H to gmlan and set speed to 33.333kbps You cant wakeup the canbus but you can read and write messages on the bus. wakeup is a 12v pulse written with CANID 000, you need a other tranceiver for that,

I want to interface serial devices on my Pixhawk 2.1 flight controller to the CAN BUS. There is not enough serial interfaces for my application. Is this the device for me? tferguson@netchino.com

Hi, could you provide its library to me to study and write the code first? Does it work with 5V Vcc? And will you put it on the Amazon later? Thank you.

Hi there~ Please check here for the library ### https://github.com/Longan-Labs/Serial_CAN_Arduino ### Power supply voltage-5v---io voltage-5v/3.3v. There is no plan to put it on Amazon for a short time.If you need a large number of purchases, please contact this email ### order@seeed.cc ### Regards

Hi! I need to read data from a TPMS MCU instaled in my trailer. It recieves temperatur and pressure data from 22 wheel's sensors. Is it possible to read them with this module?

Hello, I am not sure about it, I think it yes if it's based on CAN Bus. Thanks.
