Vr trackers: common questions
What microcontroller does the Vr trackers use?
The Vr trackers is built around the nRF52840, from the Nordic nRF family.
How big is the Vr trackers PCB?
The Vr trackers measures 30 × 30 mm, has 4 copper layers and is 1.61668 mm thick.
How many components are on the Vr trackers?
61 components, from 43 distinct parts. The full bill of materials is listed on this page.
Where can I download the Vr trackers design files?
From the 1vers1on/vr_trackers repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Vr trackers design in my own project?
The repository has no license, so all rights stay with 1vers1on. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Vr trackers 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.
