Open Source for XESS Boards

Open Source

These are the source files for some of our XESS Boards. These include the sources for host-side software, embedded firmware, FPGA bitstreams, board schematics and PCB layouts, and documention.

These files are released under a combination of GPL and Creative Commons licenses. Basically, you can take and modify these files for your personal or commercial use, but you have to release your modified files for others to use under the same terms. Check the files in the archives for the licensing details.

We also list the software tools used to make this stuff. These are either open source, free, or low-cost with a fremium version.
