# What's inside?

The board (made by Compal) seems to be closely related to the “Harmony” development board made by NVIDIA. The main CPU is a [Tegra 250 SoC](http://tegradeveloper.nvidia.com/tegra/what-tegra) which consists of

* dualcore 1GHz Cortex-A9 processor, 1 MB L2 cache * ULP GeForce GPU * DDR2 controller, 512 MB RAM (256+256 MB chips) * dual display controller (lvds+hdmi) * jpeg encoder/decoder * video encode/decoder * sound chip * and some more

Supplemental chips are (among others)

* embedded flash (type depends on the model, e.g. Toshiba [THGBM2G7D4FBAI9](http://www.toshiba.com/taec/news/press_releases/2009/memy_09_585.jsp)) * embedded controller (ENE KB926QF-D3?) * power management unit [TPS658622A](http://www.datasheetdir.com/TPS658621A+download) * Wifi ([Ralink](http://www.ralinktech.com/product.php?s=23)/MSI rt3070sta) * Bluetooth chip (optional) * 3G modem (optional, Ericsson Business Mobile Networks BV F3307 Mobile Broadband Module)
