Replay those old school retro videos games and cut the cord to build your own wireless
SNES controller powered the EZ-Key Bluefruit, Adafruits bluetooth module.
First, we'll start by taking apart the controller and unscrewing the back to remove the cover.
Carefully remove all of the components and take out the cable. Now you can carefully
remove the PCB.
Next, we need to unsolder the connections of the cable from the board .
We need to expose the common ground and solder wires that will connect the blue fruit.
Each button will need to be assigned a wire that will be soldered to the PCB.
Check out our guide for the complete circuit diagram. the link is in the description below.
A rechargeable battery will be connected to a slide switch.
A USB charger directly connects to the controller for recharging.
Now we need to solder the ground and v pin on the blue fruit to the slide switch. Test
out your solder connections and power up the blue fruit.
We spliced a JST connector to the slide switch and battery so that we can easily power the
controller and recharge the battery.
Now we can solder all of the buttons to the blue fruit. The default keyboard mapping works
great for most games.
Mark a spot on the bottom of the controller to cut out. Now we can fit the power switch
inside the controller.
Carefully put the PCB and components inside. Use a piece of foam tape to keep the battery
securely in place. Now we can snap the back cover on and put it all back together.
You can optionally 3d print a part to holster the usb battery charger. The design is available
on our thingiverse page.
Now you recharge your controller on the go, even on your laptop.
The switch at the bottom easily lets you power it on.
