The Freeplay Zero kit allows you to build your own handheld retro gaming console. You customize the look. You choose the games or software to include. You play it however you want. The end result is a gaming platform based on Raspberry Pi that looks and feels like your favorite classic handheld game console.

The Freeplay Zero comes as a kit with a Freeplay Zero circuitboard, a 3.2" LCD, a pin header (to solder to your Pi Zero), and a bag of parts needed to build the console. Here is an example of what you will receive when backing this reward.

Freeplay Zero DIY Kit example (actual kit components may differ)

The Freeplay Zero DIY kit requires the builder to supply a Raspberry Pi Zero or Pi Zero W, a battery, a micro SD card, and a GBA-style shell/housing (more on the housing/shell later). Once the pin header is soldered, the Pi Zero plugs into the Freeplay Zero PCB, as does the 3.2" LCD. You set up and add your SD card, plug in (or solder wires to) a battery, modify your shell, and you're ready to go.  

You assemble the kit to fit inside a modified shell/housing resulting in something like this next photo. Please see the previous Game Pie Advance website or the GPA forum if you would like more information on the Freeplay Zero, its features, and how it evolved.

The Pi Zero has HDMI and USB ports that are exposed through the cartridge slot access area which can be seen here.

If you want to get building your retro handheld console ASAP, the Freeplay Zero is what you want. If the power of the Pi Zero is sufficient for what you want to do (which in many cases it definitely is), the Freeplay Zero is what you want. If you want to back something that's already proven, the Freeplay Zero is what you want.
