This is the latest iteration of the well-known Proffieboard! It is the top open-source, open-hardware sound/motion/effect electronics board for lightsaber props. It contains all the electronics and software required to play audio files, show amazing LED effects and sense motion. All integrated in a tiny little board.

This new version comes with some improvements, like a newer microcontroller with more RAM and flash, USB battery charger and more! Please read our quick start-up guide for the full list of features and instructions for installation and configuration.

You can use the Proffieboard even if you don’t know much about electronics or programming, but if programming is your thing, you can optionally customize up to the last bit of the Proffieboard by writing code using the Arduino IDE (both the software and the hardware are open-source).

Optionally, with your purchase, you can choose to include a 32GB microSD card.

The board is assembled and fully tested in Italy by Artekit Labs. The microSD currently shipped is Kingston Canvas Select Plus 32GB.

NOTE 1: R1 resistor is unpopulated in the current batch of boards. If you want to use the low-current power switches you have to add a 100K resistor. Please check with the Proffieboard V3 documentation.

NOTE 2: The Proffieboard was created and designed by Fredrik Hübinette. A portion of each sales goes back to Fredrik to support his amazing work, continued development and product support.
