Keypad XD-80 5-Key Analog Module

Keypad XD-80 5-Key Analog Module

The AD Keyboard module allows you to read the states of five buttons through a single analog interface. This design lets multiple buttons share one analog port, saving valuable input pins on your Arduino or sensor extension board. Each button press produces a different voltage output compatible with the Arduino analog input, making it easy to detect which button is pressed.

Features

  • Reads up to five buttons using a single analog input
  • Saves microcontroller I O resources
  • Simple three pin connection
  • Compatible with Arduino sensor interfaces
  • Compact and lightweight design
  • Reliable voltage based key detection

Specifications

  • Operating Voltage: 5V
  • Signal Type: Analog
  • Interface Type: PH 2.5 3 Pin
  • Number of Keys: 5
  • Board Size: 68 x 33 mm

Pinout

  • VCC: Power supply input, connect to 5V or 3.3V
  • GND: Ground connection
  • OUT: Analog signal output, voltage varies based on the pressed key

How It Works

  • Each button is connected through a unique resistor value
  • Pressing a button changes the output voltage
  • The microcontroller reads the voltage via an analog pin
  • Software compares the voltage level to determine which key is pressed

Applications

  • Arduino based menu navigation
  • DIY control panels
  • Educational electronics projects
  • Human machine interface prototypes
  • Sensor expansion boards

Compatibility

  • Arduino Uno
  • Arduino Mega
  • Arduino Nano
  • Other microcontrollers with analog input support
