Rukus: common questions

What microcontroller does the Rukus use?

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

How big is the Rukus PCB?

The Rukus measures 45 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rukus?

67 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rukus design files?

From the Hung-Chi970104/rukus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rukus design in my own project?

The repository has no license, so all rights stay with Hung-Chi970104. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Rukus 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.
