Keyestudio EASY plug I2C 2004 LCD Display Module for Arduino STEAM

The Keyestudio EASY plug I2C 2004 LCD Display Module is a four-line, 20-character screen designed to display commands, data, and sensor readings for your Arduino projects. Featuring an EASY plug connector for quick wiring, it is ideal for students, educators, and makers using the EASY plug ecosystem for STEAM education.

Clear character display

This 2004 LCD module displays up to 20 characters across 4 rows with white text on a blue background. It is ideal for outputting real-time sensor readings, system status, or custom commands from your microcontroller.

Simplified I2C communication

While standard 2004 LCD screens require seven IO ports to function, this module uses an integrated I2C interface with a default address of 0x27. This reduces the required connections and saves you five IO ports for other components.

Easy plug connection

Designed for the Keyestudio EASY plug system, this module features a custom connector that allows for quick, single-cable connection. Please note that this module must be used in conjunction with an EASY plug control board.

Arduino library compatibility

The display is fully compatible with the standard Arduino LiquidCrystal Library. This makes it straightforward to program and integrate into your existing STEAM coding curriculum.

Onboard contrast control

Easily adjust the visibility of your text using the built-in potentiometer. This allows you to fine-tune the contrast of the white text against the blue background to suit your environment.

Technical specifications and dimensions

Operating at +5V, this 77.7g module measures 114mm by 60mm by 22mm. It is designed to be robust and compact for easy integration into various physical computing projects.
