[Becky] had some PS4 controllers that ended up regrettably no for a longer time practical. Having said that, most of the buttons and joysticks still appeared to be okay. As a result, she established about developing a substitute PCB to breathe new life into these previously bricked gamepads.
In the scenario of the PS4 controller, most of the buttons are of a membrane form, that talk to the principal board inside of by means of a series of contacts on a flex cable. Therefore, [Becky] developed her PCB to interface with that to study most of the buttons. A breadboard and an LED arrived in helpful to determine out which pads corresponded to which buttons on the controller. Replacement joysticks were sourced off Amazon to solder straight on to the substitution PCB.
[Becky] also took advantage of Fusion 360’s style and design resources to 3D print a simulcra of the ultimate layout. This served get the match just correct inside of the gamepad’s shell.
The substitution PCB itself functions as a breakout so that the gamepad’s controls can be wired up to a microcontroller. In this circumstance, the controller was repurposed to do the job with an RP2040 microcontroller managing a looping audio challenge. The a variety of buttons and controls hearth off samples to make it possible for basic performances.
Individuals eager to exchange the guts of their have controllers can make their personal, as [Becky] has shared the design and style data files online. If you just want to interface a PS4 controller in a considerably less invasive way, although, look at this substitute technique. Movie right after the split.
