UNDA.Xplora

Learn electronics risk-free.
Grow into a maker.

Xplora makes hardware easy to learn: start safely in 3D, then build it for real. One path, from your first LED to your own projects.

WHY XPLORA

Great kits exist.
Getting started still hurts.

For a first-timer, hardware is overwhelming, and one small mistake you didn't know you were making can mean buying the parts all over again.

BEGINNERS · CURIOUS MINDSTP1

Starting out

  • A dev kit arrives, and you still need parts just to blink an LED
  • Drivers and software to set up before your first line of code
  • Huge online projects, and no idea where to begin
  • One wrong wire, and you're paying for parts again
With Xplora

Learn in 3D first, where mistakes cost nothing and are easy to fix. Move to the kit when you're ready.

MAKERS · EDUCATORSTP2

Tinkering and teaching

  • Buying parts just to try one idea
  • Finding a kit simple enough for a whole class
  • Sharing what you know with someone brand new
  • Nowhere safe to experiment, so every mistake costs real parts
With Xplora

Experiment risk-free in Xplora3D, try any part in seconds, and give learners one clear path from the screen to a real board.

That's why we're building Xplora: so your first projects, and the hard ones after, never feel overwhelming.

HOW IT WORKS

Build it here first.
Then wire it for real.

Every part on the real board exists in the simulator, in the same place. Try a circuit safely in Xplora3D, then send it to the kit with Xplora Bridge.

THE SOFTWARE

One Firmware. Every UNDA.Xplora board.

Xplora, XploraMicro and XploraPro run the same firmware, UI and OS, so everything here works on all of them.

MADE BY PHINALABS

Three engineers. Ten years of shipping hardware.

Two mechatronics engineers and an electronics engineer design, test and build every Xplora board in-house. Xplora grew out of our classroom research in Kenya, presented at IST-Africa 2025 and published by IEEE.
