Choosing FPGA hardware
Odocrypt has been tested specifically on the Cyclone V (Technical overview)
Cyclone V doesn't refer to a specific FPGA, but rather a family of FPGAs. There are several sub-families of Cyclone V (such as GX) and hundred of different chips in that family. The boards come with a variety of different surplus components that don't affect mining capabilities.
Initial testing has been conducted on the following boards:
These can be purchased from a variety of suppliers, such as directly from Terasic or even Amazon
