The 4*4 Matrix Membrane Type Keypad Switch for Arduino, ARM and other MCU -16 Keys is a compact, cost-effective input module designed for entering numerical and character data into microcontroller… 8-pin female Berg header (2.54mm pitch) on a flexible ribbon cable.
The 4*4 Matrix Membrane Type Keypad Switch for Arduino, ARM and other MCU -16 Keys is a compact, cost-effective input module designed for entering numerical and character data into microcontroller applications. Featuring a 16-button matrix arranged in 4 rows and 4 columns (0-9, A-D, *, #), this membrane keypad allows full control using only 8 digital I/O pins on your microcontroller.
Built with a durable, self-adhesive backing, this flexible keypad can easily mount onto flat or curved project enclosures. It utilizes a standard 8-pin female Berg connector (2.54mm pitch) connected via a flexible flat ribbon cable, making it simple to interface with breadboards, development boards, and custom printed circuit boards (PCBs).
This module is widely used in electronic door locks, security pin code entry systems, menu selection panels, calculator builds, and industrial hardware control. It is fully compatible with 3.3V and 5V microcontroller platforms including Arduino, ESP32, ESP8266, Raspberry Pi, PIC, AVR, and STM32.
