README
README.md75%-Analog-Keyboard
A custom-built mechanical keyboard featuring Hall effect sensors for analog key press detection. This project uses DRV5055A4 Hall sensors, magnets mounted in keycaps, and a CD74HC4067 multiplexer controlled by a microcontroller. Each key press is measured as a variable voltage, enabling analog input functionality. RGB LEDs (WS2812B) provide per-key lighting. This project is meant to fit into Monsgeek M1 case.

Questions
How big is the DuzaKlawiatura PCB?
It measures 320.8 × 128.3 mm and has 6 copper layers, 1.6 mm thick.
What parts does the DuzaKlawiatura use?
391 parts, built around the STM32F072CBT6, SN74LV1T34DBV, DRV2605LDGS and CD74HC4067SM96. 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 DuzaKlawiatura KiCad files?
From the matres24/75-Analog-Keyboard repository on GitHub, at the commit this page was made from: the board is DuzaKlawiatura/DuzaKlawiatura.kicad_pcb and its schematic DuzaKlawiatura/Diody.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DuzaKlawiatura design in my own project?
Its repository states no licence, so its author keeps all rights: ask matres24 before reusing the design.
