Hi LorenHackPad is 3x3 macropad with a rotary encoder, an OLED display and two status LEDs.
I First started by building the schematics
then I proceded by creating the routing for the pcb
after that I realized the case
as you can see I went for a bit of particular one, since I wanted the components to be visible but also the numpad to be as minimalistic as possible and to reduce to the mininum the weight and the use of material.
and after a bit of code that you can find in the firmware folder this should be the final results
my hackpad feature a knob with wich you can regulate the volume and an oled display to show live time, date and weather. the switches are programmable and I personally chose tto assign them tto some shortcuts such as steam or spotify.
BOA:
-1 Seed xiao rp2040
-9 through-hole 1N4148 Diodes
-1 EC11 Rotary encoder
-1 0.91 inch OLED display
-2 SK6812 MINI-E LEDs
-4 M3x12mm screws

Questions
How big is the Loren HackPad PCB?
It measures 80.8 × 90.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Loren HackPad use?
27 parts, built around the SK6812MINI-E. 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 Loren HackPad KiCad files?
From the Lawrence-West/Loren_HackPad repository on GitHub, at the commit this page was made from: the board is Loren_Hackpad/PCB/LorenHackpad.kicad_pcb and its schematic Loren_Hackpad/PCB/LorenHackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Loren HackPad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
