KeebPort, a split Keyboard architecture using a single micro controller as a central "port"
Expanded SplitKbs is an open-source printed circuit board by oceanKeebs, from the oceanKeebs/KeebPort repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 66.9 × 72.6 mm with 25 parts on 51 nets, routed with 339 tracks and 21 vias.
Its parts include 7 connectors, 7 switches, 6 diodes, 2 resistors and 1 IC. It belongs with the keyboards and input boards of this library.
Keeb Port is a split keyboard architecture with a central part housing a micro controller and 6 keys (two keys can be replaced with encoders optionally). Right and left part of the split keyboard do not include a micro controller but an IO expander (MCP23017) processing the key activation information and connected via i2c to the central part. The LED control signal is generated by the micro controller and provided via a separate line to both split keyboard parts. Central and split keyboard parts are connected with TRRRS (5-pin). All layouts share the same firmware.

It measures 66.9 × 72.6 mm and has 2 copper layers, 1.6 mm thick.
25 parts. 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 oceanKeebs/KeebPort repository on GitHub, at the commit this page was made from: the board is KiCAD/Projects/KeebPort_RP2040/Pcb/Expanded_SplitKbs.kicad_pcb and its schematic KiCAD/Projects/BaseSplitTemplate/Pcb/Ortho_BaseLayout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
