You must still provide your own Raspberry PI 3/3+ or Zero W, micro-sd card, and 2.5amp or greater power supply to the Raspberry PI.
To build it yourself
Requires a Xilinx CPLD programming cable, eprom programmer, a place to prinnt pcboards, and sourcing parts. The design files are in github under the hardware folder for the project. They are in KiCad format. You should install KiCad, so you can produce gerbers, and review the schematic and pcboard layout as well as the parts mapping for the BOM. I source most parts from DigiKey, Jameco, and ebay.
