Full 104-key Keyboard with an optional screen
KiBoard is an open-source printed circuit board by colorBanded, from the colorBanded/kiBoard repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 521.5 × 206.7 mm with 319 parts on 201 nets, routed with 1,868 tracks and 95 vias.
It is built around the PCF8574AP. Its parts include 159 switches, 158 diodes and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
Full 104-key Keyboard designed as a submission for the 2026 Hackclub Stardance/Outpost Event, created using KiCAD and Fusion 360. Uses the QMK firmware for ease of use and modularity.

It measures 521.5 × 206.7 mm and has 2 copper layers, 1.6 mm thick.
319 parts, built around the PCF8574AP. 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.
From the colorBanded/kiBoard repository on GitHub, at the commit this page was made from: the board is PCB/kiBoard.kicad_pcb and its schematic PCB/kiBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
