DS2655M2 Digital I/O Module

For expanding the I/O channels of the dSPACE FPGA base boards

The DS2655M2 Digital I/O Module is an I/O module for the DS2655 FPGA Base Board. The module provides shared pins for up to 32 digital I/O channels. Some of these pins can also be used for up to 8 channels for RS232 or RS485 communication.

The DS2655M2 Multi-I/O Module can be used with all SCALEXIO FPGA boards.
