Would you please send us a photo of that?Twistplot wrote: ↑Wed Apr 01, 2020 1:31 pmHey Guys,
I bought an Raspberry Pi 4 Model B a few days back and installed Klipper and OctoPrint on it to run my 3D-Printer.
When I tried to screw it into the mounting, I accidentally slipped off with my screwdriver and hit the small parts between the power supply and the LED Lights (right above the lettering: PWR).
Is it even possible to replace the broken parts?
And if, can anybody tell me what I have broken?
Many thanks in advance
I think you would be wasting your time, and end up disappointed. Those are key components in a switching voltage regulator.Heater wrote: ↑Thu Apr 09, 2020 2:31 pmIf it were me...
1) Solder a short across the pads where the inductor was. It's only an inductor, probably for blocking high frequency noise or some such. The Pi may well work without it. The short will let the required DC through.
2) Forget about the capacitor. That is only decoupling. Bah, who needs that?
Ah, you mean that thing on the left is a switcher chip? On a quick glance I thought I was looking at something going in and out of the USB connector, seeing as it's very near by.
Maybe the broken-off parts are still lying on the floor and in a usable condition if simply reattached.

However, for someone who is not prepared it becomes quite a challenge, time sink and expense:
One will need obtain:
A soldering iron, preferably hot air station.
Perhaps a USB micro-scope or jewelers loupe.
The replacement parts. Preferably more than one of each in case of mishap. The cheapest part of the whole exercise.
Looking at those parts on my Pi I recon I could just about pull it off with my iron. Assuming the PCB pads and tracks are not ripped up. I have manged that size of SMD before, even with my big wobbly hands and terrible eyesight.
But starting from scratch i might be more time, effort and expense than it is worth. Unless one is keen on trying just for fun. Which is no bad thing of course.
