Nodemcu board could not handle 16v ?

mmaxus35 opened this issue · comments

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 ?
