CJMCU-2551 MCP2551 CAN Protocol Controller High-speed Interface Module

The CJMCU-2551 MCP2551 CAN Protocol Controller High-speed Interface Module is a high speed CAN, with fault-tolerant capabilities. It acts as an interfacing device between CAN protocol and the physical bus. The device, MCP2551 provides differential transmit and receive capabilities and is compliant with the ISO-11898, including the 24V requirements. Data transfer rate of up to 1Mb/s is achievable with this module.

The module also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources like EMI, ESD, electrical transients, etc.
