Overview
Frogpad is an open-source printed circuit board by themagicfrog, from the themagicfrog/frogpad repository on GitHub. It is a 2-layer board of 85.5 × 60.8 mm with 21 parts on 23 nets, routed with 106 tracks and 4 vias.
Its parts include 10 switches, 9 diodes and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdTHE FROGPAD
a frog-themed macropad
This is a 3x3 macropad I made for Highway/Undercity/Hackpad! I really like keyboards and frogs which is why I chose to make this project. There are 9 switches in all. Also, there is a rotary encoder in case I want to add anything later. I used KMK firmware. I did make a PCB project for the Trail, but it has been a while since I made another PCB, so it was pretty cool. I went to Meghana's hackpad workshop for it. Also, this was my first time using Onshape and Fusion360. I started with Onshape then quit and moved to Fusion360. It was a little difficult to start, but then I got the hang of it.

Questions
How big is the Frogpad PCB?
It measures 85.5 × 60.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Frogpad use?
21 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 Frogpad KiCad files?
From the themagicfrog/frogpad repository on GitHub, at the commit this page was made from: the board is PCB/frogpad.kicad_pcb and its schematic PCB/frogpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frogpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask themagicfrog before reusing the design.
