Overview
Clock front pcb is an open-source printed circuit board by QuinnFreedman, from the QuinnFreedman/modular repository on GitHub. It is a 2-layer board of 38.1 × 95.9 mm with 38 parts on 43 nets, routed with 190 tracks and 0 vias.
Its parts include 16 resistors, 11 connectors, 8 diodes and 2 switches. It belongs with the audio and music and lEDs and displays boards of this library.
README
README.mdThis project is an attempt to make Eurorack modular synthesis affordable and accessible to everyone.
This repository contains open source software and hardware schematics for Eurorack modules which are designed to be assembled easily and cheaply without any technical knowledge. Every module should be able to be assembled for around $20 in about an hour of work, even with limited experience.
To get started, check out some of the links below. Or get in touch! Send me a message at freemodular@gmail.com. Follow my reddit, Etsy shop, or GitHub.
Happy travels on your modular journey!

Questions
How big is the Clock front pcb PCB?
It measures 38.1 × 95.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock front pcb use?
38 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.
Where can I download the Clock front pcb KiCad files?
From the QuinnFreedman/modular repository on GitHub, at the commit this page was made from: the board is modules/Clock/PCBs/clock_front_pcb/clock_front_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock front pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask QuinnFreedman before reusing the design.
