this hackpad has a 12 switch matrix and 9 led "matrix" ussing sk6812 mini E LEDs


the PCB was designed in Kicad and 3D modeled with freecad. the PCB 3D model was created with Freecad's Kicadsetup addon.

the firmware is based on QMK and was coded with VS code. to compile the the firmware, first paste the qmk_firmware folder/keyboard in your QMK folder after setting up the build environment. next compile the code using this comand

qmk compile -kb "keyboard-name" -km "keymap name"
