CAN Bus 2.0

We have launched Serial CAN Bus Module years ago, which is very practial and easy to use. Now we have slightly modified the Serial CAN Bus Module, rewrote a special firmware, and release this I2C CAN Bus Module.

I2C CAN Bus Module uses I2C for communication. The module is small and flexible, which makes it quickly used in any system with an I2C interface.

The Module is based on the high-performance MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver, provides an up-to-1Mb/s CAN Bus communication rate.

In addition, there is an Atmega168PA microcontroller on the module, so that you can also program it through a USB to Serial board, and modify the firmware or write your application directly.
