Description
This four-key membrane switch keypad with a 1x4 grid is simple to operate and complements your project well. It has 5 outputs and 4 keys, using the "Scan Mode" to determine which button is pressed. It supports platforms like Arduino, AVR, PIC, STM, and Raspberry Pi. This low-profile keypad can be placed almost anywhere. The four keys are connected in a 1x4 matrix that an Arduino can easily interpret. The electrical connection is made via a flat flexible ribbon cable with a breadboard-compatible 0.1" pitch single-row female connector.
Features:
- Simple Operation: Easy to use with a 1x4 grid.
- Wide Platform Support: Compatible with Arduino, AVR, PIC, STM, and Raspberry Pi.
- Low-Profile Design: Can be installed in almost any location.
- 1x4 Matrix Connection: Easily interpretable by Arduino.
- Flexible Ribbon Cable: Provides easy electrical connection with a 0.1" pitch single-row female connector.
Specifications:
- Matrix Type: 1x4 Matrix membrane switch with FPC circuit
- Extended Keyboard: Single-chip microcomputer extended keyboard
- Performance: Precise and professionally made, stable performance
- Pad Size: 68 x 20 mm
- Total Length: 107 mm
Pinout:
- The simplest decoding method requires a digital output for each column and a digital input for each row.
- The pin count can be reduced by adding a resistor divider network and using Arduino's analog input capability creatively.
Library:
- You can use the Arduino Keypad.h Library to easily integrate this keypad into your projects.
