V1: common questions

What microcontroller does the V1 use?

The V1 is built around the STM32F405VGTx, from the STM32 family.

How big is the V1 PCB?

The V1 measures 265.5 × 132.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the V1?

267 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the V1 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 V1 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 V1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
