Grove I2C CAN-BUS Module (MCP2551,MCP2515)

Description

The I2C CAN Bus Module uses I2C for communication. Default I2C Address 0x25 and Max I2C Speed of 400k.

The board is small and flexible, which makes it can be quickly used in any system with an I2C interface.

The MCP2551 is a high-speed CAN transceiver, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard.

The MCP2515 is a second generation stand-alone CAN controller. It is pin and function compatible with the MCP2510 and also includes upgraded features like faster throughput, databyte filtering, and support for time-triggered protocols.

The I2C CAN Bus Module is based on the high-performance MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver, providing a CAN Bus communication rate of up to 1Mb/s.

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

There's Grove connect as well as Grove cable included in the kit, which allows connecting the module to your Arduino easily.
