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 CODEC Wing PCB?
It measures 81.7 × 22.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CODEC Wing use?
36 parts, built around the TL082, PCM1808PW, PCM1754DBQ 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 CODEC Wing KiCad files?
From the DiegoRosales/PCB_Designs repository on GitHub, at the commit this page was made from: the board is CODEC Wing/CODEC Wing.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CODEC Wing design in my own project?
Its repository states no licence, so its author keeps all rights: ask DiegoRosales before reusing the design.
