Wifi Deauth Watch by Travis from China since 2015. Travis tries his best to design good boards for beginners. Some of my products like ESP8266+OLED, ESP32+OLED, ESP8266+18650, ESP32+18650, and X-project, are copied by some companies and attached "WEMOS", "WEMS" and"TTGO" logos. Travis stopped these products because they are defective products. But the fake boards still existed on eBay, Ali-Express...etc.
