Connection Schemes

Wiring the LCD to the ESP8266

You can also wire your LCD to the ESP8266 by following the next schematic diagram. We’re using the ESP8266 default I2C pins (GPIO 4 and GPIO 5).

You can also use the following table as a reference.

Wiring the LCD to the ESP32

Wire your LCD to the ESP32 by following the next schematic diagram. We’re using the ESP32 default I2C pins (GPIO 21 and GPIO 22).

You can also use the following table as a reference.
