DualSense 5 Controller PCB Scans

[Kraaz]

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

My recommendation ''Mechanic VC04'' Short killer. Nice compact device.

Hi everyone,

I?m modding a DualSense controller (BDM-010) for an arcade stick and ran into an issue with the L2/R2 inputs. I noticed that L2 and R2 work with a voltage divider, setting the signal to ~0.9V at rest (instead of using a pull-up resistor).

I replicated this using two 10k resistors to create a similar voltage divider, and it works fine? but only if the BWL-010 board is connected during the controller's initialization. If I remove the BWL-010, the controller doesn't properly initialize.

Does anyone know why the BWL-010 is required at startup? Is it sending some kind of signal or specific resistance values the main board checks?

Any tips on how to bypass this dependency or emulate the BWL-010?s function would be awesome!


Thanks in advance!

Could be it doesn't like the Trigger position line floating, or they're reading the data from the EEPROMs on those boards. Either way, close to a year and a half ago now you asked about this and the same then is true now, just leave them plugged in. Unless you're making an arcade stick that is half the size of the controller shell, you're just making more work for yourself trying to get rid of them.
