The GPIF II has the following features:
▪ Functions as master or slave
▪ Offers 256 firmware programmable states
▪ Supports 8-bit, 16-bit, and 32-bit parallel data bus
▪ Enables interface frequencies up to 100 MHz
▪ Supports 14 configurable control pins when a 32-bit data bus is used; all control pins can be either input/output or
bidirectional
▪ Supports 16 configurable control pins when 16/8 data bus is used; all control pins can be either input/output or
bidirectional

Under the heatsink there is also another IO connector. This one is a 20-pin Hirose DF52 connector. This unfortunately does have to be crimped and assembled. It's a job I'm not looking forward to. The strength of this board is not the IO. There are better boards if you want that. It's in the fact that I might be able to communicate with it over PCIe. I bought these connectors anyway, but I'm in no rush to assemble them for now.
