ESP8266: I2C PORT and Address Scanner: 8 Steps
How to connect 16x2 lcd to esp8266? Ask Question 1 $\begingroup$ I have ESP8266-01 this model The two projects you link to use PCF8574 i2c port expanders. These need two pins, one for data and another for clock. An expander is a IC that takes one protocol like i2c, spi, or otherwise, and provides a number of gpio.

To use PCF8574 on ESP8266 I use this library pcf8574_esp. This number is the address of the PCF8574 expander. The last 3bit (0b00111000) can be set using address pins A0, A1, A2. Thanks to which we can connect more expanders to the same I2C bus.
