evarty/KiCADPCBThis is the PCB design for various projects. Some have associated uC code, but that is seperate. There are seperate repos for some projects under evarty. A number of these have GCode as well.
SMDClock is an open-source printed circuit board by evarty, from the evarty/KiCADPCB repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 66 × 73.7 mm with 46 parts on 56 nets, routed with 447 tracks and 29 vias.
It is built around the ATMEGA328P-AU, 74LS14PC and DS1307Z+. Its parts include 18 resistors, 9 capacitors, 4 ICs, 4 transistors and 2 connectors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

The 40 most common of 46 parts.
It measures 66 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
46 parts, built around the ATMEGA328P-AU, 74LS14PC and DS1307Z+. 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 evarty/KiCADPCB repository on GitHub, at the commit this page was made from: the board is SMDClock/SMDClock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
