Platform

LeapFrog NXP320 Platform

The LeapPad2 is part of 2 different devices that all share a common hardware platform, based around the Nexell [ http://nexell.co.kr/eng/pro/pro02.html | NXP3200] 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 LeapPad2, and contains some basic How To's and Tutorials to get you started.

Project Summary

The LeapPad2 (like the LeapsterGS) is a toy produced by Leapfrog marketed as an educational handheld gaming console for kids aged 3-9. Although it has a proprietary graphical front end, it runs an Angstrom Linux distribution on the same Cortex-A9 processor as the LeapsterGS. It also has built in accellerometer, 2 cameras, and microphone, along with a touch screen.
