Rasle kb: common questions

What microcontroller does the Rasle kb use?

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

How big is the Rasle kb PCB?

The Rasle kb measures 149.9 × 119.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rasle kb?

125 components, from 23 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 Rasle kb design files?

From the MatrixSenpai/rasle-kb 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 Rasle kb design in my own project?

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

Can I test firmware for the Rasle kb 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.
