Hi guys, unfortunately, my PS4 controller stopped charging. I was about to order a replacement battery/port when I thought, 'Let’s try charging it using the lower EXT port.'

So, I designed this port to use with Arduino pins. You just need to apply a tiny bit of CA glue to place the pins in the slots. Then, cut a USB cable and solder the black GND wire and the red +5V wire as shown in the images. Be careful with the orientation, which is why I’ve labeled it 'UP'."
