Overview
Led pad is an open-source printed circuit board by christrotter, from the christrotter/led-pad repository on GitHub, published under the MIT licence. It is a 2-layer board of 19 × 28.5 mm with 9 parts on 13 nets, routed with 191 tracks and 34 vias.
It is built around the SK6805-EC15 and SKRHACE010. Its parts include 4 diodes, 1 connector and 1 switch.

README

NOTE: v2.0 is currently un-tested, but the order is on the way.
A simple PCB featuring a light-touch five-way switch with four leds, connecting via 12-pin 0.5mm-pitch FFC. These are used as the dpad on my keyboards.
The SKRHACE010 five-way switch was used on my other pcb, and it's quite nice to use. The datasheet says it's 120gf operating force, but in practice it feels much lighter, especially compared to the Omron B3U-1000P (150gb +/-50gf).
The only challenge is the stem size is very small (1.95mm square).
I added the SK6805-EC15 LEDs at each direction because more visible is more better.

Questions
How big is the Led pad PCB?
It measures 19 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led pad use?
9 parts, built around the SK6805-EC15 and SKRHACE010. 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 Led pad KiCad files?
From the christrotter/led-pad repository on GitHub, at the commit this page was made from: the board is led-pad.kicad_pcb and its schematic led-pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led pad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
