Looking for an SoC that has bulilt in USB controller

V1 had a few issues, one of them that there had to be a whole separate chip to convert from usb to uart for the esp32 (gen 1), and in general it is kinda hard to flash a first gen esp32.

But the problem is that from my research the only SoC that has Bluetooth audio, and wifi is the first gen esp. So v2 probably won't have Wi-Fi, so no Spotify/other streaming. Which is kinda sad, but I rather have a less feature packed project, then a project that is not in a working condition like v1.

So far I have landed on the STM32WBA65CI, it has ble 6.0 and audio support, its beefy, has plenty of io, and most importantly an integrated usb controller. Maybe for a next version I will add an esp32c3 has a Wi-Fi module, but first this has to work

Also, some other stuff that I have been thinking on changing/leaving for v2:

• I will not use 0402 components, and other small components in general, it's just a pain to debug and work with, once I have a working prototype, I can do a version with small components
• Simplify the power and battery systems, I won't use a power path and a fuel gauge chip, just a tp bms and a voltage divider for the battery percentage
• I am leaving the DAC/AMP chip, and all the surrounding circuitry, except I'm using larger package sizes for the accompanying components
