I want to source power to drive a small speaker and Li-Ion charging circuit somewhere from AKSO. to me it seems most logic to take it from the USB-C 5V vbus. What pin is that and is it safe to take ±600mA from there? is any pin labeled +5V ok?
I read the main power regulator can deliver 6.5W in total, but not sure if that means I can just take it from any pin.
Also, how to deliver the power back to the akso board from the Li-Ion cells? can I just connect it back to the power pin?
