KEYES AD Keyboard Simulate Five Key Module Analog Button for Arduino Sensor Expansion Board

The KEYES AD Keyboard Module is a compact input expansion board that allows you to read five individual button states using just a single analogue port. This resource-saving design is perfect for Arduino makers, students, and hobbyists who need multiple tactile inputs without exhausting their microcontroller's digital I/O pins.

Efficient single-port analogue acquisition

By using analogue acquisition, this module maps five buttons to a single analogue port. Pressing different buttons outputs distinct voltage levels, allowing your microcontroller to identify which key is pressed while saving valuable I/O pins.

Durable Omron tactile switches

The board is populated with high-quality Omron buttons that offer sensitive, reliable tactile feedback. These durable switches ensure a long operational lifespan for your interactive projects and custom controller builds.

Seamless Arduino sensor integration

Designed specifically for the Arduino platform, this module is fully compatible with standard Arduino sensor expansion boards. It features a PH 2.5-3P interface type for secure, straightforward wiring.

Compact dimensions and specifications

Measuring just 68mm by 33mm, the module easily fits into compact enclosures and custom chassis. It outputs an analogue data signal and comes with schematics and Arduino test code to help you get started quickly.
