This is a PCB USB-C charging port to replace the original charging port on the 3DS-XL, this port works with USB-C to USB-C cable charging so you don't need to worry about having a USB to USB-C cable.

The Installation jig allows you to solder down the castellated holes while holding the PCB in perfect alignment, a thumb screw is provided for easy assembly and disassembly of the jig.

While I've tested the jig on a few 3DS XL boards I can't guarantee a perfect fit so some sanding may be required, do to the heat of the iron I consider the jig to be a mostly single use item. In testing I get ~5.1 V and .75A while charging. I do not preserve the old gold contacts of the 3DS XL.

Here is my installation process:

1. Disassemble your 3DS XL
2. Remove the PCB.
3. Use a hot air station @290C (no more than 30-40 seconds is necessary) to remove the original charging port (preheat the board with a hot plate @168C or use the hot air station to preheat the board)
4. Clean the PCB pads
5. Put the top half of the jig in first.
6. Using the pins snap the bottom half of the jig in
7. You can lightly secure them with the provided thumbscrew or swap this with the next step.
8. Firmly place the USB-C board in the top half the jig, it should lay flat.
9. Apply some flux to the castellated holes
10. Use a decent amount of solder to the affix the board. I have my iron at 295C for this.
11. Disassemble the jig (you may need to use flush cutters break apart the top part of the jig if it fused with the bottom half).
12. Touch up each pad and heat up the pads near the edge so that the solder on the pads under them melts.
13. Heat up the board again with the hot air station to make sure everything is settled and make sure all the pads are in contact (no more than 30-40 seconds @290 C)
14. Use a multimeter to make sure that VCC isn't shorted to GND.
15. Take some flush cutters and snip away at the plastic 'gate' of the old charging port.
16. Put the bezel on the USB-C port and reassemble the 3DSXL 17 (optional). keep cutting down the plastic if you find it's not fitting to your liking, not much needs to be done so do be careful.
