Product Description

MR-MINI-4x4KEY is a 4x4 matrix keyboard module. It is 10-PIN MRconnect ready. It has 8 pins to interface with MCU (microcontroller). PIN1-PIN4 (COLUMN) is INPUT for MCU to reads the status of key pressing. PIN5-PIN8 (ROW) is OUTPUT for MCU to send logic LOW to scan key press on each row. MCU operation is sending logic LOW into each key’s ROW (PIN5-PIN8). The MCU is then reading the status of key press from PIN1-PIN4. If any key is pressed, the status read logic LOW, otherwise the logic is HIGH. PCB size is 2.20” x 1.70”

Features: 

• 10-PIN MRconnect ready
• +3.0V to +5VDC supply voltage
• On-board pulled-up resistors
• Small and compact in size
• Four mounting holes on each corner

Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad. Check the tutorials tab for links to an Arduino library and example code.

Description:
We include a 7-pin extra-long header strip so you can plug this into a breadboard with ease.
