DualSense 5 Controller PCB Scans

[Manavie]

I see,
I'll look into the IOVDD pins some more. To clarify writing a 1 to the VOLTAGE_SELECT register would make it use1.8v signal levels, which would fix the issue of sending 3.3v to the DS5 and frying it. The OLED screen (SSD1306) using says that Vdd for IC logic can be from 1.65V to 3.3V, and the Vcc for panel driving should be from 7V to 15V, but I believe that is regulated on the OLED screen module itself, so I think the OLED screen could still work?
Another thing is that, when I just put a voltage divider down to 1.8v to the buttons, they seem to work fine on the OLED? Although this requires a divider for every button lol. I'm not sure if it's because I'm not checking for a "high" input for the logic on my screen, I'm rlly just drawing a bunch of circles as it's default state and then filling them in if the button is set to LOW.

Looking online, it seems there could be some trouble trying to supply with 1.8v due to how the board is*, and that it would also mess up USB functionality according to the DS so I'd still need to give that a 3.3v supply, and I'm not too sure how to supply it to just that one pin. One suggestion that forum post recommends is to use level shifters, could that work? It'd keep the inputs to the DS5 at a 1.8v when not pressed but still 3.3v when going to the board.

*From raspberry pi forums
"Looking at the Raspberry Pi Pico schematics I see that it is possible to tie down 3V3_EN and drive an external, lower voltage on 3V3. unfortunately, according to the schematics, 3V3 is shorted to USB_VDD, that must be driven with 3.3v nominal.
Another option would be to disconnect IOVDD from the 3V3 signal, however, the RP2040 datasheet indicates that all the IOVDD pins must share the same voltage."

Hello, I have a similar problem. r1 remains pressed all the time. can you help me? (bord BDM020)

@ viewrush - If you mean the R2 is always pressed, then try removing this Capacitor first (bottom side of board) and retest.

Top side of the board.

Hey everyone. I have 2 questions for you regarding a BDM-030

Where is a good spot to take the RSY Signal (marked red) , cause the trace is broken right next to one of the stick anchor points. I could try to repair it, but it always end up shorting it to the hole.

And can i just bridge along the blue line to get power for RSX ?  Also, where is the original supply Point of that spot ? From the via next to it i cant find a valid spot

[RDC]

That's 3 questions.


1. No easy spots for RSX (red) or RSY (blue). Either have to remove the solder mask on the trace somewhere and solder a wire there to run back to the RSX, or go back to the first via and do the same.




2. Yes

3. From an internal layer, which comes from the PMIC

[SchwarzerAfri90]

Thanks for the fast reply. Indeed that were 3 questions 

I will take the via then. Followed the traces last night but wasnt able to propely do anything due to lack of conentration.
A buddy gave me this one to install hall-effect sticks after the first 2 normal ones he replaced himself. Missing 2 vias already but luckily they were just ground.

But i messed up the signal trace myself while desoldering the hole next to it. I hope i can do it, cause i dont have a digital microscope and this is about half the size of an HDMI trace , which i did a few times now.
I have a half-decent soldering and hot air station, i think i can do this one.

Is there any chance to get some links for newer revisions into here or another pictures with more informations like the ones for the BDM-010 ?
Or where do you get all that information from ?

Sure is, you can hit the New Topic or Reply button and post it.

Any images or info that I post comes from when I run across a new version and have the time to work on it.

Hi. I see  V1 and V2 microphone flex, are they interchangeable?

[SchwarzerAfri90]

Did they came up with another revision ? I never seen one marked with "B"

I just got i as a replacement for another white one with stick drift (came bundled with the console, they shall take care).

Anyone know where I can find a scan of the BDM-040 mobo? I see BDM-030, but the options button is different on the 040.

[TheOneForTheJob]

I just want to clarify, the reason I wanted a scan was because I'm looking to solder a back button to the options button. On the bdm-030, you can see where the line goes and can solder to that point (I don't know the lingo sorry), but for the bdm-040, it goes under the sie chip so I can't see. I'll send a picture.

Idk how to upload a picture directly but this one shows what I meant in my other comments.

[TheOneForTheJob]

OK, I ended up reading through all the pages of this post and saw rdc's advice of using an xacto knife to pop off the options button and solder ot it. I wasn't exactly sure what he meant by that. I was goofing around with an old ps4 controller's reset button since its the same and I took off the orange and silver circle. Here's what it looks like:
https://imgur.com/a/PWYUZMw

Is he talking about that circle in the middle or is he talking about taking off the whole plastic square surrounding it too?

[RDC]

It depends which way they installed it, but typically the center is the button line and the outside will be ground. Solder a wire to the center and touch it to ground somewhere and see if the button activates.

[TheOneForTheJob]

Yeah, I got options and share working but I :censored:ed up the via I was soldering to bind to touchpad. Here is the via:

The other side of the via is very close to the ribbon cable port and so I'm hesitant to solder to that. Is there any other touchpad vias on the 040 board?

Hello everyone, I need a little help, the O button stays pressed continuously on the BDM 10 motherboard. Everything looks normal on the motherboard.
I examined it under a microscope, but couldn't find anything. Where could the problem be?

Try to change the circuit flex cable.

[Kraaz]

Try to change the circuit flex cable.

The problem is not the flex cable; even on the bare motherboard, it stays pressed.

[LethalPrime]

It is shorted somewhere. You?ll have to find where the short is and fix it.

[RDC]

@ Kraaz - Top side of the board, remove the marked capacitor and retest.

Thank you for your response, but unfortunately, it didn't work; it remains the same. Sad

good morning. I have a BDM 030 board. It works and charges normally when the battery has some charge. The problem comes when the battery is completely discharged. I connect it via USB and it doesn't do anything at all.
I tried different batteries and it does the same

[LORDCHECHE]

Hi i have a controller where i tried to fix drift by soldering new Hall sensor sticks, for some reason it works fine when i connect it to my pc with the cable, but when i connect it with bluetooth for some reason the touchpad triggers the share button and the left stick doesn't go down, Y axis works only with positive values otherwise it goes only to -1. This only happens with a bluetooth connection, if connect it by usb it works fine. Any help is appreciated because i have no clue what could be happening.

There's a BDM-050 now, too: https://medium.com/@killscreen.io/bdm-050-revealed-whats-new-in-sony-s-latest-ps5-dualsense-4a3f8148a0f4

hi,
i removed this cap, but short on pads still presented, R1 still jamed
where this small leg goes?

[RDC]

It's pretty much a straight shot to the MCU.

BDM-020 R1 BUTTON TOP



BDM-020 R1 BUTTON INNER 2



BDM-020 R1 BUTTON BOTTOM

[goxon1981]

So my only option is to try reballing.
Two controllers came to shop, same batch, same console, same problem

[RDC]

Pretty hard for that to short to ground up under there. It's on the second row in from the bottom, could just flux it there good and try a reflow to see what happens. Could be it was a PCB defect and that trace is shorted to ground internally or somewhere. If a reflow or reball doesn't fix one, I'd shoot 1.8v and some current into the R1 trace there and see what gets warm or pops. Also, if you do remove the MCU, test the trace for the short then before reinstalling.     

[goxon1981]

I tried with voltage, but my PSU on 1.8V give only 0.06A output for shorts. Need to buy better PSU. This is not suitable for this kind of jobs

[goxon1981]

Desoldered IC, short is in IC.
Cant find it on Aliexpress
So, controllers go to parts
