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)

  1. robu (verified owner)

    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.
