A CAN-BUS module for reliable long-distance communication

The CAN (Control Area Network) communication protocol enables you to network various embarked devices using your microcontroller, at relatively high speed. Data transfers remain reliable and secure even over long cables. That’s why the CAN-BUS is commonly used in robotics to connect various circuits and electronic boards.

Easy to use in all your electronics and robotics projects

Connect your robot via CAN-BUS to any sensors or actuators you can think of and turn it into the most autonomous and agile creation. This Serial CAN-BUS from Seeed Studio connects to your Arduino board (or Raspberry Pi, Beaglebone, etc.) by plugging the Base Shield (or GrovePi+, Grove Cape, etc.) to your microcontroller. Arduino users also get easy access to a complete code library.
