Overview
First kicadfile is an open-source printed circuit board by clavinohou, from the clavinohou/first-pcb-keypad repository on GitHub. It is a 2-layer board of 140.5 × 19.1 mm with 25 parts on 44 nets, routed with 295 tracks and 35 vias.
It is built around the ATMEGA32U4-AU. Its parts include 7 capacitors, 4 resistors, 4 diodes, 2 switches and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdVolume mixer and audio controller (first pcb design)
Goals:
- Create a pcb
- Music controls
- Song skip
- Song play
- Song pause
- Volume control - though rotary encoder
Design:
Its basically an Arduino Pro Micro just put in the form factor that I wanted. It features 4 MX style contacts for your switches to sit on. There is also a pinout for a rotary encoder for volume adjustment. In the final design I plan to just solder wires to the rotary encoder since the knob I want wont be able to sit right next to the switches. I will make a branch with the code that I eventually use, as well as another branch for the .stl I eventually create, but for now I'm just making sure the circut board actually works.

Thanks for looking at my project lmao

Questions
How big is the First kicadfile PCB?
It measures 140.5 × 19.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the First kicadfile use?
25 parts, built around the ATMEGA32U4-AU. 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 First kicadfile KiCad files?
From the clavinohou/first-pcb-keypad repository on GitHub, at the commit this page was made from: the board is first kicadfile.kicad_pcb and its schematic first kicadfile.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the First kicadfile design in my own project?
Its repository states no licence, so its author keeps all rights: ask clavinohou before reusing the design.
