Questions
How big is the Guitarray control board PCB?
It measures 79 × 142 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Guitarray control board use?
757 parts, built around the CMOD A7-35T, OPA1604AID, DS90LV011AHMF and LMH1208RTV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Guitarray control board KiCad files?
From the IIP-Group/polymap repository on GitHub, at the commit this page was made from: the board is electrical/guitarray_control_board/guitarray_control_board.kicad_pcb and its schematic electrical/guitarray_control_board/guitarray_control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Guitarray control board design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
