The XGameStation Pico Edition 2.0 is a build-it-yourself game development kit based on the technologies of its bigger brother, the XGameStation Micro Edition. The XGS Pico Edition 2.0 comes with a solderless breadboard and parts as well as the Pico PCB Add-On Kit.
After you build the breadboard version you can solder your unit together and have a completely portable and reprogramable embedded game system. Complete instructions covering assembly, architecture, and programming of the Pico Edition comes with the kit on CD.
The Pico Edition may be simple, but it packs a punch with a Ubicom SX28 microcontroller running at a blazing 80.000MHz. It comes with a 7-Segment readout, 15-pin interface, A/V jacks, and a built in directional game pad for a completely portable mini-game console.
The XGameStation requires an SX-Key programmer to reprogram. They are available from XGameStation.com or Parallax. You might also want a USB-to-Serial adapter; we recommend this one from keyspan.
