Less is more…

Like its successful predecessor, but with a lower profile to fit into smaller projects. This kit converts 7-12V into 3.3 or 5V to power your microcontroller and connected components without being tethered to a wall outlet.

Change the regulated voltage of the kit between 3.3V and 5V with a switch on the PCB to provide the correct voltage that your circuit requires. Includes multiple terminals to power circuits at the regulated voltage or at the input voltage.

Unpack. Solder. Go!

Skip the hard tasks and continue with the fun part of assembling the bits & pieces of a PCB. Start by selecting the included components, then solder it together and see your project come to life.

Never miss a part.

Ever tried assembling a PCB from the BOM (Bill of Materials) itself? We did, and we know how hard it is to collect all the needed parts and components. We already did the hard work for you by sourcing all the parts and components needed so you can get straight into creating a finished, working PCB.

Built by makers, for makers.

The Quantum team is comprised of curious makers and tinkerers, and this DNA can be found within each of our hardware and software products. Our DIY Kits are no exception. We designed our Kits to work well past their first impression, meaning you will have access to step-by-step documentation, high-quality open-source 3D Files, sample code, and so much more. Using your DIY KIT unleashes the true power of your making capabilities and introduces each of your individual projects to a multitude of integration possibilities.

Compatible with Arduino.

We made our new DIY Kits compatible with Arduino to make sure more people have access to these awesome boards. The Arduino files can be found in our GitHub repository and are also linked down below.


Perfect projects for you

Our inspiring team of makers have just scratched the surface with these showcase projects. What will you make? A weather-station, TV IR remote, lighting controls, smart outlets, robotics, games or a remote controlled car. The possibilities are endless.


  • Do I need to buy any additional parts?

    You just need a 7-12V battery or power source and then you’re ready to go.

  • Do I need to use the Quantum platform to use this product?

    No. This is an independently used power supply that can power any piece of electronics at 3.3 or 5 V DC.
