Noraneko52r: common questions

What microcontroller does the Noraneko52r use?

The Noraneko52r is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Noraneko52r PCB?

The Noraneko52r measures 228.8 × 98.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Noraneko52r?

173 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Noraneko52r 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 Noraneko52r 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 Noraneko52r 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.
