Product Overview
This module features two tactile push buttons mounted on a compact PCB with a 4-pin header interface. Each button provides a momentary digital input signal, making it ideal for user interaction in embedded systems.
 
Integrated resistors ensure stable signal output, eliminating the need for external pull-up or pull-down components.

Package Includes
1 × Dual Push Button Module
1 x 4 pin header(un-soldered)
 
Compatibility
Works seamlessly with:
Arduino (UNO, Nano, Mega)
ESP8266 / NodeMCU

FPGA boards (Basys 3, Tang Nano, etc.)
 
Working Principle
Each push button acts as a momentary switch
When pressed:
The corresponding signal pin changes state (HIGH or LOW depending on configuration)
When released:
The signal returns to its default state via onboard resistors
Can be directly interfaced with:
Microcontrollers
FPGA GPIO pins
Digital input circuits
 
Notes
Output logic (HIGH/LOW) depends on wiring configuration
Debouncing may be required in software for precise applications
Ensure correct VCC and GND connections
