Questions
How big is the Picotouch grid PCB?
It measures 180 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Picotouch grid use?
170 parts, built around the TS20, H11L1, SK6812MINI-E and HS96L03W2C03. 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 Picotouch grid KiCad files?
From the todbot/picotouch_grid repository on GitHub, at the commit this page was made from: the board is hardware/picotouch_grid/picotouch_grid.kicad_pcb and its schematic hardware/picotouch_grid/picotouch_grid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picotouch grid design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
