Hello, I am Travis Lin, a maker from China.
I started making ESP8266, ESP32 development boards since 2015.
I try my best to design good boards for beginners. Some of my products like ESP8266+OLED,ESP32+OLED,ESP8266+18650, ESP32+18650, X-project, they are copied by some company and attached "WEMOS","WEMS"and"TTGO" logo.
I stopped these products because they are defective products. But the fake boards still existed on Ebay, Ali-Express...etc.
I wish you can support my products because I am improving the IOT development boards for makers.
