Not working NodeMCU
Voltage regulator: AMS1117 (H1618) - I do not know what the second number is
USB2Serial: CP2102 (1806+)
Capacitor? (yellow component): 107J H110C

Working one
Voltage regulator: AMS1117 (H1938)
USB2Serial: CP2102 (1916+)
Capacitor? (yellow component): 107J 33F2

Could this be the reason?

Does the NodeMCU work when you try to upload a simple code? Like the basic LED blinking? If so, then it is not damaged.
