Description
USB PCM2902 chip based circuit for internally connected USB soundcard. Used for PI project PCBs to add integrated sound. Uses usb 2.0 4 pin and outputs 3 pin LRG. Pictured are a spare tester I have and what it lookes like on a Game Boy Advance PCB for an Orange PI CM5. Standard 5V D+ D- G input and audio line out. The line out output can have a potentiometer added between it and the amp input to control volume. I usually just cut and paste it to retain the parts markings and it gets added into the autorouting.
