- Tue Dec 22, 2020 8:40 am #89905 Some LCDs have 0 volt to 5 volt logic levels. (character LCDs is one example) Using 0 volt to 3.3 volt logic levels can cause problems with these displays. (many will work)

I use I2C to control character displays. I use voltage level translators (on the SDA and SCL lines) between the 3.3 volt powered ESP8266 and the I2C chip driving the signal lines of the 5 volt powered display
