Questions
How big is the 8x8 PCB?
It measures 297 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 8x8 use?
250 parts, built around the MCP619-I/SL, MCP3008-I/P, PCA9956BTWY and WP154A4SEJ3VBDZGC/CA. 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 8x8 KiCad files?
From the matiyau/screen_antenna repository on GitHub, at the commit this page was made from: the board is hardware/electronics/PCB/8x8/8x8.kicad_pcb and its schematic hardware/electronics/PCB/2x2/2x2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 8x8 design in my own project?
Its repository states no licence, so its author keeps all rights: ask matiyau before reusing the design.
