Q4 RAF help


So I installed the Brooks UFB into my Q4, and it went well, all the buttons work. Only problem is I have no idea how to get home button connected to the board. What do I need, and what do I do?
Thanks for all the help guys



I actually had this same problem and had to figure out a (very inelegant) solution on my own through trial and error. My board’s a Hori FC4 but the principle should be the same: ground is soldered to the middle solder point I’ve drawn an arrow to and labeled in the picture below, and the signals corresponding to the buttons on the front of the stick are each soldered to the prongs in the right-side plastic port (they are labeled on the home button PCB). The buttons on the front work with this set up when I have the switch set to PS3/PC; they don’t work when it’s set to 360 for some reason.

I’m sure there’s a better/cleaner way to do this, but I couldn’t figure it out and this was quick and easy.



Extremely easy.
Pretty much the same thing I did here (I’ve since changed the cables however, to insulted ones from adafruit: https://www.adafruit.com/products/1949, and hooked up mode/turbo to L3/R3 )


Except try these cables.

One side is smaller than the other side, so you can use whichever one snags on the “PS” pin easier the tightest, although both will work. You may need to hotglue the 2.54mm end if it’s not secure.

Then take the other end, cut the connector off, then strip the wiring by like 1/4th of an inch, and then screw the bare wire into the Home/Guide/PS screw terminal on the brook ufb :slight_smile:

I went with the all headers soldered option, so as you can see, I also hooked up TPkey to Select on the front panel, and have L3 and R3 also (Turbo, and Mode). If I ever need to flash the firmware, I have an extra wire already screwed into “Select” screw terminal, then I remove the TPkey to Select wire jumper and put on the original select jumper to screw terminal select for F/W flashing.

In the picture, I didn’t connect Mode yet, and Turbo is TPkey instead of L3.

@par124 : if you don’t have a way or any ability to solder, you can also look up GND by wire crimps on the right pins, like i have in my photo, and hook it to the UFB that way. The front panel is common ground.
@fishsticks420 : it doesn’t look like your UFB has the all headers presoldered, so you won’t have a way to use Mode, Turbo and Switch, without soldering. I went with all headers presoldered so I was able to make use of TPkey, R3 and L3.

TPkey is rather important on PS4, and R3/L3 are important in Street fighter 5.
