PCM2912a+TPA152 USB audio module

Overview

USB audio + amplification module based on TI's PCM2912a+TPA152 chip.

PCM2912a: Audio codec chip with USB interface, mono microphone input and stereo headphone output. The data sheet is as follows: https://www.ti.com.cn/document-viewer/cn/PCM2912A/datasheet/abstract# SLES2302197

TPA152 75mW stereo analog input headphone amplifier, the data sheet is as follows: https://www.ti.com.cn/cn/lit/ds/symlink/tpa152.pdf?ts=1648596881050

After the early boarding, I found an error in welding and jumped a wire directly. The drawing has not been updated. Thanks to the attentive NicolasYM for reminding me, the new drawings have been updated and can be used directly.

There are a few empty boards left, and you need to jump a line. If you need them, they can be sent for free, and you just have to pay for the postage.
