Introducing the I2C CAN Bus Module 鈥?a powerful and versatile communication solution for a wide range of applications.

This module uses the I2C protocol for communication and is built with a small, flexible design that makes it easy to integrate into any system that has an I2C interface. It is based on the high-performance MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver, allowing for communication at speeds up to 1 Mb/s.

One of the key features of this module is the Atmega168PA microcontroller, which allows for programming via a USB to Serial board and the ability to modify firmware or create custom applications. This opens up a wide range of possibilities for various industries such as:

  • Vehicle diagnostics: The I2C CAN Bus Module can be used to connect to a vehicle's onboard diagnostic system and read diagnostic trouble codes, as well as monitor various sensor data such as engine RPM and vehicle speed.
  • Industrial automation: The module can be used in industrial automation systems to enable communication between different devices and control systems on a factory floor.
  • Robotics: The module can be used in robotic applications to enable communication between the main controller and various sensors and actuators, allowing for precise control and coordination of movement.
  • Medical equipment: The module can be used to connect different components in medical equipment, such as patient monitors, imaging equipment, and laboratory instruments, to enable data collection and analysis.
  • Building automation: The module can be used in building automation systems to enable communication between different devices such as lighting, heating, ventilation, and security systems.
  • Transportation: The module can be used in transport applications, such as on boats or buses, to enable communication between various systems, such as engine control, navigation, and passenger information display.
  • In addition, this product has received certification from CE and FCC, ensuring its quality and reliability. And for customer who looking for a protective case, we also released an version of the CANBed encased in an aluminum alloy housing.

    Don't let communication limitations hold you back. The I2C CAN Bus Module offers an easy and flexible solution for all your communication needs. Try it out today and see the difference it can make for your application.
