PCB design using TLV320DAC3203

[CTCL]

I have designed a PCB for adding an audio output to a Flipper Zero device after verifying that an I2S interface was available through the GPIO headers. This is my first post after hearing about the forums for years.

I am a beginner to circuit design so there may be a lot to fix. Any ideas to improve the design will be appreciated.

PCB design, BOM and schematic are attached.

Looking at the schematic .png file, it looks like the voltage regulator inputs are not connected to any supply.

I did not notice that. I updated the PCB and schematic. Thanks.
