Rev2: common questions

What microcontroller does the Rev2 use?

The Rev2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Rev2 PCB?

The Rev2 measures 95 × 77 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Rev2?

194 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rev2 design files?

From the Churrosoft/Dashdash repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rev2 design in my own project?

Yes, under the terms of its MIT license, which Churrosoft chose for the repository.

Can I test firmware for the Rev2 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.
