The PlayStation 4 Pro and PlayStation 5 have orange, blue and white leds to indicate the status of the console.
Boot - Blue
Idle - White
Rest - Orange
The PS4 Pro / PS5 leds and their transistors are on a separate pcb connected by a 6 pin ribbon cable.
What I want to do is replace the white and orange leds with red and green so that I can output any color of my choosing at each state. To do this i'm guessing I need some kind of micro controller pcb programmed with a custom script. To be placed between the PlayStation motherboard and the led pcb.
- The leds are always connected to 5v.
- Each led signal goes to the base pin of an unknown model transistor .
- When each led is fully on the transistor base pin gets 3.3v and 450 microAmps.
- When the led pulses it goes between 0-3.3v and 0-450 microAmps on the transistor base pin.
Obviously I need to emulate the signal each transistors base pin is expecting with the micro controller.
Lets assume the leds are now:
Boot - Blue
Idle - Green
Rest - Red
So if I want my idle state led to be purple (R+B=Purple) I need to tell the micro controller when it sees a 3.3v 450 microAmp signal on the idle led input pin to output a 3.3v 450 microAmp signal on both the blue and red led transistor base output pins.
Does this sound like something that can be easily done with readily available cheap micro controllers, if so what would you recommend?
