This is a RoHS compliant I2C Serial LCD Daughter board that can be connected to a standard 16×2 or 20×4 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 16×2 and 20×4 line character modules support it too.
This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on the internet for using this board with Arduino. Do a search for “Arduino LCD PCF8574“. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one it’s own address)
Specifications and Features:
- 5V power supply.
- Serial I2C control of LCD display using PCF8574.
- Backlight can be enabled or disabled via a jumper on the board.
- Contrast control via a potentiometer.
- Can have 8 modules on a single I2C bus (change address via solder jumpers)address, allowing.
- Size ：41.6 x 19.2 mm.
Package Includes:
1 x IIC/I2C Serial Interface Adapter Module

Works great, but a reminder about the following:
1. The module I2C address is 0x27 not 0x3F (i.e. a +1 to what another reviewer said).
2. Make sure you turn the contrast knob to the appropriate setting for your display. I spent a good few hours debugging it before I remembered the contrast control. The default is too low for the 1602 (green backlight 16×2) display.
With the ESP32 Feather, you can connect the 5V (Vcc) line to the “USB” header pin which provides a 5V supply.
