GCAN-PLCcore-M7 development suite uses for running GCAN-PLCcore-M7 module rapidly. The circuit we offer can simplify the hardware design user develop. 

This suit has several kinds of function interfaces including power interface, one-channel Ethernet interface, one-channel RS232 interface, one-channel RS485 interface, two-channels CAN interfaces, 8-channels DI interfaces, 8-channels DO interfaces, one-channel USB serial, one RTC battery holder.
 

The board also has a 2*22 double row needles and uses for leading the rest pins in the module including power and IO interface. User can connect signal to external circuit you developed to satisfy all kinds of demands.
