Questions
How big is the Macropad12 PCB?
It measures 93 × 94.8 mm and has 4 copper layers, 1 mm thick.
What parts does the Macropad12 use?
153 parts, built around the MS88SF3-NRF52840, GT-EVA01AA-L1, HC-FPC-05-10-24RLTAG and FDV303N. 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 Macropad12 KiCad files?
From the rontsang/macropad repository on GitHub, at the commit this page was made from: the board is macropad12.kicad_pcb and its schematic USB_battery-charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad12 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rontsang before reusing the design.
