STM32F411_USB_AUDIO_DAC_PCB

PCB for USB Audio DAC using STM32F411/401 IC and PCM5102A

This is a simple PCB for the perfboard-and-firmware project created by har-in-air at https://github.com/har-in-air/STM32F411_USB_AUDIO_DAC.

This project aims to create a very small, high-quality USB-C DAC, using KiCAD to make the PCB and OpenSCAD to make a simple 3D-printable enclosure. The firmware from the aforementioned project will be used as-is.

Soldering this project may be difficult; take a look at the perfboard option using the STM32 Black Pill and PCM5102A module if soldering small SMD components is outside of your capabilities.
