Questions
How big is the Touch PCB?
It measures 100.1 × 161.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Touch use?
112 parts, built around the LM13700M and LM1117-3.3. 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 Touch KiCad files?
From the microresearch/allcolours repository on GitHub, at the commit this page was made from: the board is own_touch/touch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Touch design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
