Module Large IOexpander is an open-source printed circuit board by sullyjason, from the sullyjason/interactiles repository on GitHub. It is a 2-layer board of 39.6 × 36.4 mm with 15 parts on 36 nets, routed with 199 tracks and 20 vias.
Its parts include 3 connectors and 1 switch. It belongs with the lEDs and displays and home automation and IoT boards and the ESP32 boards of this library.
3×5 grid of TL1 NeoPixel switches (7.5mm² each). 4-layer board with MCP23017 I/O expander mounted directly on the underside. Pinout is non-obvious due to space constraints — refer to schematic.

It measures 39.6 × 36.4 mm and has 2 copper layers, 1.6 mm thick.
15 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 sullyjason/interactiles repository on GitHub, at the commit this page was made from: the board is Button_Modules/Large/Module_Large_IOexpander/Module_Large_IOexpander.kicad_pcb and its schematic 2x2 Interactiles/PCB/Controller PCB/RGB 2x2 with WS2811.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask sullyjason before reusing the design.
