Review on Aideepen Development ESP8266 External Connector by Sirious Cavalli

Put a little sample code on the board that will send the Wi-Fi signal strength back to Home Assistant so I can check the signal strength at the board's location. It sewed normally. Moved in. It started, ran for a few seconds, gave a reading and died. I touched the board and WOW! she was hot Very very hot. I screamed, jerking my hand away and quickly knocked it out. Powered by USB phone adapter (iPhone, 5V). It's deserted and I'm afraid to plug in a second one.
