SlimDash rev1: common questions

What microcontroller does the SlimDash rev1 use?

The SlimDash rev1 is built around the RP2040, from the RP2040/RP2350 family.

How big is the SlimDash rev1 PCB?

The SlimDash rev1 measures 157.1 × 131.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SlimDash rev1?

137 components, from 18 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 SlimDash rev1 design files?

From the mizma/SlimDash 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 SlimDash rev1 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which mizma chose for the repository.

Can I test firmware for the SlimDash rev1 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.
