While hardware documentation is ready, and available for anybody to see and use, software documentation page is currently empty. However the company has already worked on NXP (previously Freescale) i.MX6 boards for several years, and provided Linux distributions built with the Yocto Project as well as Android image and source for their iMX6 Rex board.


OpenRex is developed under Creative Commons Attribution 4.0 International license and all materials can be used for personal and commercial use, as well as for education with one exception: commercial educational activities such as paid courses, trainings, or videos as this is how FEDEVEL gets its income: paid hardware design and PCB layout courses. This limitation does not apply to universities.

The board will be mass-produced in Q2 2016, but so far pricing has not been decided, and the company is still asking people how much they’d be willing to pay for the board on OpenRex product page. The price range is likely to determine which i.MX6 processor will be used, and how much RAM will be soldered to the board.
