Gravity: Analog ADKeyboard Module V2

The Gravity: Analog ADKeyboard Module V2 is a five-button input interface designed to read multiple key states using a single analog pin. It is ideal for students, makers, and educators looking to add interactive button controls to microcontroller projects without using up multiple digital I/O lines.

Single-pin analog key detection

This module reads the states of five separate keys through a single analog input. This design significantly conserves valuable I/O resources on development boards like the Arduino.

Flexible operating voltage

The keyboard module supports both 3.3V and 5V power supplies. This makes it directly compatible with standard 5V microcontrollers as well as modern 3.3V development platforms.

Expansion board compatibility

The module is designed for smooth integration with Gravity I/O expansion boards. It allows quick prototyping and reliable connections for interactive electronics and menu navigation.

Compact board dimensions

Measuring just 55 mm by 33 mm, the board offers a space-saving physical footprint. It fits easily into custom enclosures and educational project builds.

Included connection cable

The package includes one ADKeyboard module along with a compatible analog sensor cable. It provides everything required to connect the board directly to your controller.
