This is a very cheap macropad(4 usd) you can use for typing your emails or passwords.
It has USB C
Components used:
RP2040 Zero(from Waveshare or chinese copy)
https://a.aliexpress.com/_EQsV7VT
4 key flexible nupad
https://a.aliexpress.com/_EJjBgLL
maybe some glue and hot glue
Will be adding links soon.
Probably any small dev baord such as arduino nano or mini esp would fit but i did not test. I made it specificaly for the rp2040 zero as they have usb C
The code you upload with arduino IDE
Here is the code and schematic on the github page: https://github.com/AllexRaresh/MacroPad
Print at 0.2mm layer height
There are 3 versions of the base:
Ultra slim(good luck)
Normal version(for the version with unsoldered pins)
Taller version
There are 2 versions of the Top:
Normal(hollow, less fillament, more space)
Filled(worse)
You have to glue the PICO upside down so that the usb c goes trough the hole
I recommend using the taller version to have more space for the cables.
Will add better versions after feedback
