overheating
Posted: Thu Nov 26, 2020 12:05 am
I seem to be having trouble getting good ESP8266 units. Or, is it me?
I am new to Arduino stuff. I have tossed about 20 D1 Mini and NodeMCU units in the last 2 months.
The latest failure I was monitoring myself closely; no loose wires, not powering any peripherals, simple motor control sketches (separate power source) using IR remote and WebServer, power from PC USB. I was troubleshooting the sketch, which meant loading it about 10 times, unplugged it for dinner, It overheated as soon as I plugged the USB back in.
It is the part under the metal cap, not the voltage regulator.
Any ideas what is going on?
