We’ve all done it before, accidentally shorting Vin (Voltage input) and GND (Ground) on an ESP8266. I have done it as well thinking: How should this break an ESP8266? It turns out by destroying the reverse polarity diode. These are not my findings btw, by these people figured it out<\/a>. But let’s get to work. Here is the current state:<\/p>\n\n\n\n

Broken diode marked with a red rectangle<\/figcaption><\/figure>\n\n\n\n

The thing marked with a red box is the broken diode. This is the thing that needs to be fixed. First step: Remove it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In the next step, we will replace it with a new diode called wire.<\/p>\n\n\n\n

This fixed my broken ESP8266 and brought it back to life. I hope someone can use this.<\/p>\n","protected":false},"excerpt":{"rendered":"
