README
LM317 Power Supply/readme.md#LM317 Power Supply with split supply Rev 1.3
This is a simple LM317 variable power supply with an extra circuit that creates a split supply to power opamps and stuff. It's theoretically capable of sourcing like 1 amp, but I haven't tested that yet. To generate the split supply I used a voltage divider and an Op Amp from Linear Technologies called LT1206 as a buffer. Here is the link of the article that explains how to generate split supplies with a Virtual Ground. Virtual Ground Circuits

Questions
How big is the Quetzalcoatl PCB?
It measures 99 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quetzalcoatl use?
70 parts, built around the ENC28J60-H, PCM1807PW and PLL1705. 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 Quetzalcoatl KiCad files?
From the DiegoRosales/PCB_Designs repository on GitHub, at the commit this page was made from: the board is Quetzalcoatl/Quetzalcoatl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quetzalcoatl design in my own project?
Its repository states no licence, so its author keeps all rights: ask DiegoRosales before reusing the design.
