AudioDeck

This project is based on an off the shelf ESP32 Dev module: It utilizes an sd card reader, a PCM5102, and MAX97220. Utilizing these components it will act as an mp3 player. For user input there is an oled moduel, a rotary encoder, and a mechanical keyboard switch. For power it will run off a single 18650 cell that feeds into a tp4056, which then feeds into a boost converter. There will be capacitors to smooth the voltage and reduce noise. The end goal is to play audio through my headphones. Moreover it will be built on a perf board pcb with elegant hand routed solid core wire as traces.
