1st Gen Nano Clone Diagram
 

I love this clone. Only one thing i hate about it is its durability. My family and I have 3 nano clone and all of its USB port broke. Everything works fine other than battery charger and transfer because the usb doesn't work. Does anyone know or have a descriptive diagram of the nano? There's 4 pins. It's so small, but i'm gonna try to resolder it back to normal.
