Overview
Pps splitter is an open-source printed circuit board by folkertvanheusden, from the folkertvanheusden/pps-splitter repository on GitHub. It is a 2-layer board of 47.5 × 65.5 mm with 16 parts on 13 nets, routed with 172 tracks and 43 vias.
It is built around the 74HC04D. Its parts include 6 connectors, 4 resistors, 1 capacitor and 1 IC. It belongs with the radio and wireless boards of this library.
Main components
1README
README.mdThis piece of electronics is a splitter for PPS signals. From 1 to 4 and also including a nice header that allows you to measure the delay introduced by the buffer IC. I've obtained the schematic from https://klubnl.pl/wpr/en/artykuly/proste-zrodlo-sygnalu-1pps/ Did not test it yet.

Questions
How big is the Pps splitter PCB?
It measures 47.5 × 65.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pps splitter use?
16 parts, built around the 74HC04D. 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 Pps splitter KiCad files?
From the folkertvanheusden/pps-splitter repository on GitHub, at the commit this page was made from: the board is pps-splitter.kicad_pcb and its schematic pps-splitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pps splitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask folkertvanheusden before reusing the design.
