A USB C dock with included headphone DAC
July 26th: Designed basic schematic for USB hub.
Today I made the basic schematic design for the USB C hub. At first I was going to make it with 3 USB C ports and a single USB A but I decided I don't need USB A so much so I designed it with just USB C.
Total time spent: 2h
July 27th: Added DAC
I decided that I want to add a headphone audio output on this because just a USB hub seems too simple. I did some research and decided I'm going to use the PCM 2902. Datasheets are so confusing.
I started to wire things up but i'm rather confused on how the input and output are supposed to be connected. So far I have basically been copying the example in the datasheet.
Total time spent: 3h
July 30th: Finished Schematic
I finished the schematic with the DAC.
Total time spent: 4h
