I was found a memory upgrade on an old esp201 but in the process of removing the old chip I blew off what looked like a resistor next to the user pins. If it is a resistor does anyone know what value it is so that I can replace it

If you share the picture of your board,marking the damaged part, may be someone can come up with help.

I don't use that board myself but an on-line picture shows it is pretty simple. Here are my guesses.


Below the memory chip I think are two leds and two 12K resistors.
The capacitors either side of the crystal oscillator would typically be about 10pF
The resistor to the right of the oscillator is a 12K used to ties RES12K pin to GND
The capacitor above the CPU is probably a 3.3V power decoupling capacitor. One could verify this by checking the pads with a meter and if so they would go to the 3v3 and GND pins. Typically they would put either a 4u7 or 10u capacitor here.

But as said a picture of the damaged board would be helpful

Thank you very much, let me try the 4u7 capacitor
