The 1×3 Button Array Module is a compact and easy-to-use input interface designed for developers, makers, and embedded system engineers. It features three tactile push buttons arranged in a single row, providing a simple and reliable way to add user input functionality to embedded projects.

Each button is connected to its own signal line, allowing individual digital input reading from a microcontroller. With clearly labeled pins, onboard resistors, and mounting holes, this module is well suited for quick prototyping and integration with platforms such as Arduino, ESP32, STM32, and other microcontroller-based systems.
