README
Power Supply/README.mdPower Supply
This power supply uses an L7812, L7912 and LM7805 as voltage regulators to create +12V, -12V and +5V power rails. Each voltage regulator has a 1uF capacitor tied to ground on both the input and output as well as 3 4700uF capacitors as buffer from the power input.
There are 6 IDC, 16 pin, headers for powering modules. The board has each row marked and a number '1' near the red stripe row.

Questions
How big is the Power Supply PCB?
It measures 249.3 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power Supply use?
42 parts, built around the L7812CV, L7912CV, LM7805 and PJ-059BH. 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 Power Supply KiCad files?
From the Jumballaya/Modular-Synth repository on GitHub, at the commit this page was made from: the board is Power Supply/Power Supply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power Supply design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jumballaya before reusing the design.
