Overview
Pinstripe is an open-source printed circuit board by null-ll, from the null-ll/pinstripe repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 323.8 × 123 mm with 186 parts on 113 nets, routed with 2,031 tracks and 48 vias.
It is built around the ATMEGA32A-PU and DS1307Z+. Its parts include 69 diodes, 7 resistors, 5 capacitors, 1 IC and 1 crystal. It belongs with the keyboards and input and lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

Setting the Time
In the default keymap, pressing Fn+T (custom keycode KC_SETTIME) will put the keyboard into time setting mode. Enter the time in the form HHMMSS (hour, minute, second) in this mode to set the RTC time. This time will be stored in the RTC module, even when the keyboard is powered off, for as long as the battery lasts.
For custom keymaps, add the keycode KC_SETTIME to a key (preferably not on the base layer).

Questions
How big is the Pinstripe PCB?
It measures 323.8 × 123 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pinstripe use?
186 parts, built around the ATMEGA32A-PU 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.
Where can I download the Pinstripe KiCad files?
From the null-ll/pinstripe repository on GitHub, at the commit this page was made from: the board is pcb/pinstripe/pinstripe.kicad_pcb and its schematic pcb/pinstripe/pinstripe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pinstripe design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
