Innodisk EGPC-B201 - M.2 2260 or 2280 dual isolated CANbus 2.0/J1939

2 CAN 2.0B Ports, 1Mbps Data Rate, -40 to +85C


Controller Area Network (CANbus) is a serial communication that was originally designed for the automotive industry. As Internet of Things (IoT) becomes a trend, CANbus is widely applied in aerospace, defense, medical, LED lighting and building automation systems. IoT application is clean, simple, and delivers low-cost wiring architecture. It also provides error detections, signaling, and fault tolerance making it more secure and reliable.

In light of this, Innodisk designed the EGPC-B201 CANbus module. It provides dual inputs and galvanically isolated circuits. This allows for an increase in CAN 2.0B interface that native CPU design does not support and is compatible with 2.0A. The module supports SAE J1939 high layer protocol as an option.

When considering the system upgrade and output expansion in industrial computers, system architects can use EMUC-B201 to immediately obtain CAN ability via M.2 interface, in either 2260 or 2280 B-M key. This diminishes the challenges that builders have when redesigning the system’s motherboards.
