How it happened
Recently I was working on a device with Blynk application in which my device will burn crackers using Blynk. I wanted to create a safe environment for burning crackers. There was a dilemma to power Nodemcu with a battery first I used a 38650 lion battery but it didn't provide sufficient power to Nodemcu. Than I connected two 38650 battery in series than it was working fine for half a minute. But later it started became hot but than I removed the power supply immediately and powered it with 3.3v charger than also it was heating and still.
My research
I researched a lot and also changed the S4 didode with IN4007 but it is still heating and malfunctioning. I checked all the parts but they were not shorted. What's the problem with my Nodemcu why is it heating and not working properly. With regards Naman
