Overview
PANEL is an open-source printed circuit board by a-lange, from the a-lange/Buffered-mult repository on GitHub. It is a 2-layer board of 40.3 × 128.5 mm with 4 parts on 13 nets.
README
README.mdThis is a buffered mult, made in Kicad for 8HP format.
It is tested, and works.
For now there is a few minor issues:
- power connector is too close to the edge, so it overhangs a tiny bit. So use an unkeyed pin-header and note that -12v(red stripe) is towards the edge of the board.
- GND is missing on the top jacks, easily patched manually.
The front panel is reversible, the back has a simpler layout with no logo, text or copier.
Use it however you like.
The text says 'copier' in Norwegian, and the creature on the bottom is the friendly "ullmann"(wool-man).

Questions
How big is the PANEL PCB?
It measures 40.3 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PANEL use?
4 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 PANEL KiCad files?
From the a-lange/Buffered-mult repository on GitHub, at the commit this page was made from: the board is PANEL.kicad_pcb and its schematic mult.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PANEL design in my own project?
Its repository states no licence, so its author keeps all rights: ask a-lange before reusing the design.
