The Adafruit I²C Controlled + Keypad Shield Kit lets you drive a 16×2 character LCD and read 5 navigation buttons using only two I²C pins on your Arduino. This frees up the 9+ digital pins that a standard LCD connection would require, while still allowing other I²C devices to share the bus.
The shield includes 4 directional buttons plus a select button, making it ideal for standalone projects with their own user interface. It supports standard blue/white LCDs as well as RGB backlight LCDs, with the ability to switch between 8 backlight colours (red, yellow, green, teal, blue, violet, white, and off).
Key Features
- I²C Control – Drive the LCD and read buttons using only 2 pins, leaving other pins free
- 5 Navigation Buttons – 4 directional plus select, queryable through the Arduino library
- RGB Backlight Support – Control RGB backlight LEDs for 8 colour options
- Shared I²C Bus – Connect additional I²C sensors, RTCs, and other devices alongside the shield
- LiquidCrystal Compatible Library – Drop-in replacement for the built-in Arduino LCD library
- USA-Made PCB – High-quality shield with all components included
Ideal For
- Standalone Arduino projects with user interface controls
- Menu-driven embedded systems
- Sensor readout displays with navigation
- Learning I²C communication and LCD interfacing
Package Contents
- 1× I²C LCD Shield PCB
- 5× Navigation buttons
- Header pins and all required components

Jargon buster
Plain-language definitions for the technical terms used above.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
