I just received another shipment of ESP-01 Modules but unfortunately one of them is broken

There's a part missing right next to the SoC, from looking at the other modules I'd say it's a capacitor.
Please check the attached PNG to see the damaged part! sorry for low quality

this wikipedia picture has a lot better quality:

the big brown capacitor to the lower left of the ESP8266 chip

Any ideas? i found some schematics but no corresponding layout, so it's hard to tell which capacitor it is. Would really like to repair that little guy, would be a waste to throw it out because of a missing capacitor.

This shows only three capacitors (0.1uf, 1uf and 10uf) going from power to ground (you can meter them out to make sure which three they are.) The higher valued one should also be the largest one physically. So that cap is probably the 10uf.

well, you never stop learning.
I guess I need to buy a new multimeter. mine doesn't have the capacitance symbol on it.


thank you for your help
