Mayflash F300 Detachable USB C mod

Fixed cables are a PITA, so I wanted to make the USB cable on my fightstick detachable.

I used a dremel to widen the existing notch that was used for the original USB cable.

My wishlist of improvements for this are as follows

• A top cover for the breakout board, rather than making use of electrical tape

• Some way of attaching the mount to the case to avoid the flex found when inserting the USB C cable

As for wiring this all up, see the close-up pictures.

• Red: VBUS

• Black: GND

  • Both GND wires from the mainboard are wired up to the single GND pad on the breakout board

• White: D-

• Green: D+

BOM

• 2x M2.5x6 machine screws

  • Only for mounting the breakout board to the print. The print piggybacks off of the USB A port's mounting posts and screws 

• USB C breakout board

  • I used this breakout board and it has the resistors required for USB 2.0 already installed

Optional BOM

• JST-XH 5-pin male connector

  • for making a custom connector wire rather than stripping and frankensteining the existing USB-2 cable

• JST-XH wire crimper

  • Pre-crimped wires included in JST kits like this  are far too short for this, so you either need to solder them together, or make your own wires

• JST-XH 6-pin male & female connectors

  • So you don't have to solder the wires directly to the breakout board
