LeapFrog Pollux
Platform

The Leapster Explorer is part of 3 different devices that all share a
common hardware platform, based around the Pollux
SoC. The platform page contains information generic across these
devices, and it is recommended that you refer to that page as it is a
good starting point to understanding the Leapster Explorer, and contains
some basic How To’s and Tutorials to get you started.

Project Summary

The Leapster Explorer (like its predecessor the Didj) is
a toy produced by Leapfrog marketed as an educational handheld gaming
console for kids aged 4-9. Although it has a proprietary graphical front
end, it runs a generic Linux distribution on the same ARM9-based
processor as the Didj. Console access to the Explorer is achieved using
the same method as found on the Didj.
