Noraneko42l: common questions

What microcontroller does the Noraneko42l use?

The Noraneko42l is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Noraneko42l PCB?

The Noraneko42l measures 293.2 × 106.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Noraneko42l?

145 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Noraneko42l 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 Noraneko42l 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 Noraneko42l 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.
