About the Vulpes minora PCB

Vulpes minora is an open source RP2040/RP2350 PCB design by sadekbaroudi, published on GitHub. It is a 2-layer board measuring 124.7 × 96.1 mm, with 67 components from 20 distinct parts.

Its main chip is the RP2040 Controller, from the RP2040/RP2350 family. Other key parts include the nice_nano and AP1603WG-7. By type, the board carries 25 diodes, 21 switches, 5 ICs, 5 jumpers, 4 connectors and 3 capacitors.

It belongs with the keyboards designs in this gallery.

Vulpes minora: common questions

What microcontroller does the Vulpes minora use?

The Vulpes minora is built around the RP2040 Controller, from the RP2040/RP2350 family.

How big is the Vulpes minora PCB?

The Vulpes minora measures 124.7 × 96.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Vulpes minora?

67 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 Vulpes minora design files?

From the sadekbaroudi/vulpes-minora 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 Vulpes minora design in my own project?

The repository has no license, so all rights stay with sadekbaroudi. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Vulpes minora 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.
