RGBDuino RGB Keypad V1.0 16-Key Expansion Board

The YINGHUA RGBDuino RGB Keypad V1.0 is a 16-key expansion board designed for Duino microcontroller projects. It adds a 4x4 matrix of white round keycaps labelled 0-F and per-key RGB illumination to your build. The board targets makers, students and hobbyists who want tactile input and visual feedback without designing a custom PCB. It draws power from a 5 V supply connected to the host board.

Simple header connection

Installation consists of wiring the keypad's VCC and ground pins to a 5 V DC source on the Duino board and connecting the matrix rows and columns to digital I/O pins. The supplier notes a 0-1 cm dimensional variance due to manual measurement, so mounting holes may not align perfectly with pre-drilled enclosures. No retail packaging or mounting hardware is included, so builders must provide their own standoffs or adhesive.

Suits Duino-based projects needing a compact

This keypad suits anyone adding a light-up control surface to a Duino-powered device such as a 3D printer interface, macro pad or learning kit. It is not suitable for builders who need a larger key count, different keycap profiles or a fully enclosed module with integrated mounting points. Users requiring a different voltage level or a matrix larger than 4x4 should look at other input options.

Questions about this item

How do I confirm the RGBDuino RGB Keypad V1.0 is working after connecting it to my Duino board?

Apply 5 V DC to the VCC input, then press each of the 16 keys; the corresponding RGB LEDs should light and the Duino serial monitor should register key codes 0 through F.

What ships in the box and what must I source separately?

The package includes one RGBDuino RGB Keypad V1.0 with 16 white round keycaps installed; you must supply a compatible Duino board, a 5 V DC power source and any mounting hardware.

Which version or capacity of this keypad should I choose for my project?

Only the V1.0 model with a 4×4 matrix of 16 keys is offered, measuring 165.86 mm by 86.87 mm, so select this single variant when you need a 16-key RGB keypad for Duino boards.
