Questions
How big is the TutelPad PCB?
It measures 61.9 × 65.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TutelPad use?
40 parts, built around the ATMEGA32U4, USBLC6-2SC6, WS2812B and SMF5.0CA. 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 TutelPad KiCad files?
From the 0xCB-dev/0xCB-TutelPad repository on GitHub, at the commit this page was made from: the board is PCB/smd-rev1.0/TutelPad.kicad_pcb and its schematic PCB/rev1.0/TutelPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TutelPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0xCB-dev before reusing the design.
