Nodemcu board could not handle 16v ? #34

Open mmaxus35 opened 6 years ago

mmaxus35 commented 6 years ago

I have bought a esp8266 nodemcu board, yet it is burned and smoked out when i connect 16v to Vin pin and GND to GND ? Diodes are burned as it is shown in the figure ?

I could not understand why ? Because diodes and AMS1117 has maximum power input rating as much as 18V ? nodemcu

Most devkits have a max input voltage closer to 5v. A very few can handle up to 12v, but those get fairly warm. It’s the other components, mainly the voltage regulator, that limit it.
