Noraneko42c: common questions

What microcontroller does the Noraneko42c use?

The Noraneko42c is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Noraneko42c PCB?

The Noraneko42c measures 280.4 × 121.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Noraneko42c?

127 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Noraneko42c design files?

From the darakuneko/Noraneko repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Noraneko42c design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Noraneko42c 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.
