Nyx: common questions

What microcontroller does the Nyx use?

The Nyx is built around the RP2040, from the RP2040/RP2350 family.

How big is the Nyx PCB?

The Nyx measures 304.3 × 108.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nyx?

107 components, from 20 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 Nyx design files?

From the HorrorTroll/Nyx 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 Nyx design in my own project?

Yes, under the terms of its GPL-2.0 license, which HorrorTroll chose for the repository.

Can I test firmware for the Nyx without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
