The Ouya microconsole is build on Nvidia Tegra 3 (T33) SoC, featuring a quad-core 1.7 GHz ARM Cortex-A9 CPU and a ULP GeForce GPU, paired with 1GB of DDR3 RAM and 8GB of internal flash storage. Running a modified Android 4.1 (Jelly Bean) OS with a custom launcher, it aimed for open-source gaming via a digital storefront. This implementation is mostly based on upstream Linux device tree and fragments of work done by previous developers.
