PCIe-CAN-GPIO

The PCIe-CAN_GPIO contains a wide assortment of industrial I/O. The board is capable of being used in a PC style motherboard to expand capability or it can be a stand-alone board for closed loop control or monitoring. It has all its system I/O mapped into PCI space and available to the host computer.

For applications requiring closed loop control, there is a 32 bit, 125 MHz RISC processor built into the FPGA with associated SDRAM and FLASH. The processor can be programmed with a readily available integrated development environment.
