Arduino Push Button Module 2/3/4/6/8 Keys, 3.5V-5V Digital Input Electronic Block with Optional Plastic Housing

Arduino Button, Push Button Arduino

OMRON Type Big Button Keypad Module for Arduino DIY Project, Digital Output Keypad Board

This YwRobot large push button electronic building block is compatible with Arduino and equipped with OMRON-style tactile switches. The module works at 3.5V or 5V, with digital level output: low level when pressed and high level when released. Multiple variants are available, including 2-key, 3-key, 4-key, 4-way cross keypad, 6-key and 8-key. You can select the bare PCB version or the version with a protective bottom housing.

It supports Arduino, Raspberry Pi, STM32 and other microcontroller boards. The buttons provide a comfortable pressing feel and stable signal output. Standard 3mm mounting holes are reserved for easy installation. The terminal adopts 3P SVG socket or pin header for simple wiring.

Suitable for Arduino DIY projects, robot control, human-machine interaction, game controllers, electronic teaching experiments, smart equipment input and electronic competition projects.
