The SparkFun SerLCD is an AVR-based, serial enabled LCD that provides a simple and cost-effective solution for adding a 20x4 Black on RGB Liquid Crystal Display into your project.

This version of the control board has been updated to include an ATmega328P to handle all of the screen control, which means that a separate backpack is no longer required!

This display can communicate in using either serial, I2C, or SPI and comes equipped with a Qwiic connector, bringing serial LCDs into the Qwiic ecosystem, which simplifies the number of wires needed and allows your project to display all kinds of text and numbers.

The on-board ATmega328P AVR microcontroller utilizes 11.0592 MHz crystal for greater communication accuracy with adjustable baud rates of 1200 through 1000000 but is default set at 9600. The firmware for this SerLCD is fully opensource and allows for any customizations you may need.


  • Since the SerLCD is a 3.3V device, please make sure you convert to 3.3V logic depending on your chosen microcontroller or single-board computer. Otherwise, you may risk damaging your board.
