OLinuXino

OLinuXino is an open hardware single-board computer capable of running Android or Linux designed by OLIMEX Ltd in Bulgaria.

The project's goal was to design DIY friendly industrial-grade Linux board which everyone can reproduce at home. It leverages widely available hand-solderable components which are reasonable to purchase in low quantities, housed in TQFP packages. The project's CAD files are hosted on GitHub, allowing everyone to study and customize them according to their needs.^[1]

Initially OLinuXino was designed with EAGLE. In March 2016 the first boards designed with KiCad became available as OLIMEX Ltd announced plans on switching development to Open Source CAD tools.^[2]

A13

The Chinese company Allwinner released in April 2012 Cortex-A8 SoC in TQFP package, this was spotted immediately by OLinuXino developers and they start working on OLinuXino board based on A13^[6] Three OLinuXino boards with A13 processor were released:
