Hi, while replacing the stick in my controller I accidentally took out a capacitor that connects the rumble trace with ground. I was wondering if its necessary and what value does it have. Thanks in advance.
Technically yes, but if some of those are damaged the thing shouldn't even work. Large Cap is decoupling on the battery rail. The two Resistors next to that are the divider so the MCU knows the battery voltage, small cap is just filtering for that. Last Resistor on bottom is Pull-Up for the Battery Temp sensor. The only -020 I have here is already stripped clean so I can't measure any of those, but I imagine they are the same values as the -010 board. 150k - Vertical Resistor 100k - Horizontal Resistor, closest to connector7.5k - Bottom ResistorCap values are not critical.
Out of circuit is the only way to get the correct value for most components. On the -010, the Horizontal one measures around 59k, but the Vertical one starts off around 70k, ends up around 130k in circuit.
@ponziflex - Either one will technically work, though you'll get far more resolution from a DAC, just make sure it will work properly from a 1.8v source.
For ps4 are 3.7mm, for ps5 i don't know, maybe 3.3mm? check the size with the gauge and then write smd tactile button on AliExpress and order it, obviously you pay less if you take the compatible one and the original one, the original 20 piece ps4 smd smd buttons were sold for 4 usd, I got 100 pieces for 2.7usd
