LightStick: common questions

What microcontroller does the LightStick use?

The LightStick is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the LightStick PCB?

The LightStick measures 23 × 36.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LightStick?

22 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the LightStick design files?

From the f0reachARR/music-light-stick repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LightStick design in my own project?

The repository has no license, so all rights stay with f0reachARR. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LightStick without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
