compact usb-i2s dac using rp2040 and max98360a for powering speakers, like index bmr drivers
- I forgot the silkscreen for usb pins, but they should be clear from below images.
- 0201 components suck to work with.
- intended to use with a usb-c cable, however the CC wire needs 5.1K pull-down to ground which I forgot about
firmware for the device is at https://github.com/sctanf/picoamp
