I'm using these with ESP8266 for an IoT LED course at a local store. They also work fine with the ESP8266's 3.3V logic level, at least when powered by the individual LEDs from the ESP8266's 3.3V USB power supply. I bought 2 boards of 100 pieces. Tested every LED on one board and about 20% on the other board, no defects.
