Prep the PCB
Instead of crimp terminal connectors, we will solder wired directly to the board. Prepare the board by tinning each pad with a bit of solder.
Now will prepare to solder connections from the PCB to the Feather microcontroller.
- Cut a short length of wire for each contact on the Atari PCB, and one for ground. I've color-coded them similarly to the original wiring. Since I didn't have brown wire I substituted it for yellow
- Strip a bit of insulation off of the ends of each wire
Solder the Feather Wires
Following this guide, solder each of the direction wires and the fire button wire to the pins of the Feather microcontroller:
YELLOW: RIGHT to 16
WHITE: UP to 15
BLUE: DOWN to 7
- GREEN: LEFT to 11
ORANGE: FIRE to 30
Since we'll be sharing ground among a few components, wait to solder in the black wire in for now.
Feed the slide switch and USB breakout board from the inside of the joystick through the hole and then to the outside.
Feather to PCB Traces
- Now place the microcontroller inside of the joystick body as shown and placed the original PCB onto its mounting holes
- Trim the pin connection wires to a proper length to fit, with just a bit of extra wiggle room. If the wires are too long they may make it difficult to fit everything inside
- Next, solder the connecting wires to the original Atari PCB as shown
- Use a little bit of double stick foam tape to secure the battery inside of the joystick body as shown
- Plug the battery's JST connector into the Feather microcontroller. If the controller turns on, go ahead and flip the switch to turn it off
Tuck everything in neatly and close the case, being careful not to allow the button spring to fly off!
Secure the joystick with the four original screws.
Switch and USB Port
- To secure the slide switch and USB breakout to the joystick's cable port, use some double stick foam tape
- To maintain the look of the controller, you can blacken the edges of the tape with permanent marker
Now, you'll be able to plug in the USB cable whenever you need to charge the battery.

Excellent! The joystick is now wireless and ready for play.
