Solderix - The LEGO of Electronics and Robotics You’ve Been Waiting For

 If you've ever dreamed of an educational platform that combines the fun of LEGO with real-world electronics and robotics — meet Solderix. This innovative modular prototyping system brings hands-on STEM learning to life with a creative twist: all components are actual printed circuit boards (PCBs), designed to snap together and be reused across multiple projects.

Whether you're a parent looking to introduce your child to electronics, a teacher seeking engaging classroom tools, or a hobbyist exploring new ways to build, Solderix is a powerful new platform that promises to revolutionize how we learn and prototype in the world of tech.

Solderix is a modular electronics platform designed for easy prototyping, learning, and experimentation. Think LEGO, but with real PCBs — each module has a specific function (motors, sensors, controllers, etc.), and they all connect together using metal standoffs and screws. You only need a screwdriver to get started.

It's entirely reusable, expandable, and educational, aimed at helping users of all ages (kids, students, educators, hobbyists) to understand the core principles of electronics, mechanics, and robotics.

At the heart of the Solderix experience is Zoom, their base RC car kit. Built using multiple PCB modules — including motor drivers, power systems, and controller interfaces — Zoom is fast, agile, and completely customizable.

Zoom runs on the SolderBit (a custom controller powered by the ESP32 chip), but it's also compatible with the BBC Micro:bit, making it highly accessible for classrooms and STEM programs.

This isn’t just an RC toy — it’s a real engineering platform.

• Real PCBs, not plastic: Learn electronics through the actual components used in industry.
• Tool-free creativity: Connect boards with metal standoffs. No soldering needed.
• Visual programming: Use SolderBrix, their online drag-and-drop tool, for coding projects — perfect for beginners.
• Upgradable ecosystem: Servo motor modules, line followers, cameras, sensors, and even a terrain truck shell.
• Designed for education: Encourages planning, fine motor skills, 3D visualization, and hands-on problem-solving.

Whether you're starting with the basic car kit or going for the Zoom Exploration Pack, you’ll have everything you need to build your own robotic vehicles, sensor systems, or even custom games.

Pair it with the Sideye camera and you can even stream live video from your Zoom vehicle. Future updates promise game development tools, more modules, and complex robotics (like a robotic hand!).

Solderix is brought to you by the team behind Pulsar Labs, the first Croatian company to send hardware into orbit. With over 70,000 units sold globally and a proven track record in aerospace and industrial design, the people behind Solderix are no strangers to quality engineering.

Solderix is currently crowdfunding on Kickstarter with multiple reward tiers. This is your chance to be part of the next big thing in educational robotics and STEM tools.

If you're a maker, educator, or just a curious mind, Solderix deserves your attention.
