OLinuXino

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

A10-OLINUXINO-MICRO Open Source Hardware Linux computer

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]

A10S

edit

In November 2012, Allwinner released a new A10S processor with HDMI and Ethernet and dual-core A20 processor.The A13 has no native Ethernet capability, so the A10S processor was chosen for new OLinuXino boards.[7]
