Product Overview
This compact Push Button Module is designed for quick and reliable digital input interfacing in embedded and electronics projects. It integrates a tactile push button with an onboard resistor network, allowing flexible configuration as either a pull-up or pull-down input without additional components.
 
Ideal for prototyping, training kits, and production-ready designs, this module eliminates breadboard complexity and ensures stable signal output.

Package Includes
1 × Push Button Module (Pre-assembled)
1 x 3 pin header(un-soldered)
 
Compatibility
Works seamlessly with:
Arduino (UNO, Nano, Mega)
ESP8266 / NodeMCU
ESP32

Working Principle
When configured as Pull-down:
Default state → LOW
Button press → HIGH
When configured as Pull-up:
Default state → HIGH
Button press → LOW
The onboard 4.7kΩ resistor ensures a defined logic level even when the button is not pressed, preventing floating inputs.
