« on: September 10, 2018, 04:45:03 pm »
Hi, im wondering if anyone here would have any information on how to add a usb charging circuit to this chip. I have a battery and can run the chip with it but i dont fully understand what pins i would be wiring to where on the chip, it is a standard usb b circuit, i will add an image. Any help appreciated!
