Questions
How big is the Wacom PCB?
It measures 56.5 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wacom use?
36 parts, built around the AVR128DB48 and TP1. 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 Wacom KiCad files?
From the Mr-Bossman/wacom_tablet repository on GitHub, at the commit this page was made from: the board is kicad/wacom/wacom.kicad_pcb and its schematic kicad/sensor/sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wacom design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mr-Bossman before reusing the design.
