Primis Versipellis: common questions
What microcontroller does the Primis Versipellis use?
The Primis Versipellis is built around the NRF52833_QDXX, from the Nordic nRF family.
How big is the Primis Versipellis PCB?
The Primis Versipellis measures 50 × 26 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Primis Versipellis?
25 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Primis Versipellis design files?
From the Nieko27/Frame-Workshop repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Primis Versipellis design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which Nieko27 chose for the repository.
Can I test firmware for the Primis Versipellis 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.
