This is RP2040 (Raspberry Pi Pico) driven calculator using mechanical switches based on the MX-format which doubles as an HID-numpad if wanted.
This is my very first real physical and polished project and thus im very proud of it as a 15 year old :)
PCB
The 2 sided PCB was designed in kicad and some rookie experience! You can find the design files in the kicad folder and production in gerber.
Installation 📀
Before installing, it is very important to flash circuipy on your Pico. You can download the newest version here
Now there are two options:
Installer (only linux tested!):
- Open a terminal
- run
git clone https://github.com/Jonathan357611/Calc-V1.git - ... and now
./installer.sh. The installer should copy all necessary files to your Pico! - Done!
Manual
- Clone the repo
git clone https://github.com/Jonathan357611/Calc-V1.git - Take these files: code.py font5x8.bin lib/
- And copy them on your Pico!
That should be it. If you have any troubles installing it, hit me up!
HID Numpad
Want to use it as a numpad? Easy!
Just set HID to True in line 7 in code.py!
Other
Any contributions in code, installation and PCB are very welcomed :) I'll try my best to fix any issues you run into.

Questions
How big is the Calculator PCB?
It measures 98 × 133 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Calculator use?
26 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 Calculator KiCad files?
From the jonatfm/Calc-V1 repository on GitHub, at the commit this page was made from: the board is kicad/calculator.kicad_pcb and its schematic kicad/calculator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Calculator design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonatfm before reusing the design.
