Many projects claim to be “open source hardware” (OSHW) after they’ve released the schematics in PDF format, and source code. But the definition of OSHW has a few more requirements, which is practise means you’ve got to release schematics and PCB layout in the native format, not only in PDF, as well as the gerber files, and the bills of materials. Open Source Hardware can also truly be useful, if you can source the components. and for example, Broadcom BCM2835 processor might be impossible to procure, especially in small quantities, and that makes the Raspberry Pi unsuitable as an open source hardware platform. Existing companies / associations dedicated to OSHW include Arduino, Beagleboard.org, Olimex, etc.., and today Radxa has joined the club by releasing all hardware designs files for Rockchip RK3188 based Radxa Rock Pro and Lite development boards (2014 version) under a Creative Commons Attribution 4.0 International License. This could be the very first Chinese company to do so, at least for ARM development boards.
You can get the hardware design files on Radxa’s oshw repository in github. Let’s see what’s they’ve released:
- Schematics in Orcad 16.5 and PDF formats
- PCB layout (.dsn) to be open with PADS 9.5
- Manufacturing files including the Gerber files, Bill of material (BOM), components placement, etc…
- Mechanical drawings in DXF format
It looks good to me, did they forget anything?
