The BatPad

After watching The Batman, I thought that I should make a 3x3 macropad for it. It has 9 switches, 9 mini leds, a rotary encoder and a 0.91 OLED screen. I decided to use QMK firmware for this project. I learned ALOT from the project as it is my first time making a PCB and modeling a case. Fusion360 was new to me in the beginning, but now I feel more comfortable using it.

Questions

How big is the BatPadV2 PCB?

It measures 98.4 × 87 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BatPadV2 use?

43 parts. 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 BatPadV2 KiCad files?

From the Doubtfull/The-BatPad repository on GitHub, at the commit this page was made from: the board is PCB/BatPadV2.kicad_pcb and its schematic PCB/BatPadV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BatPadV2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask Doubtfull before reusing the design.
