Storre: common questions

What microcontroller does the Storre use?

The Storre is built around the ProMicro, from the AVR/Arduino family.

How big is the Storre PCB?

The Storre measures 304.8 × 146.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Storre?

195 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Storre design files?

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

Can I use the Storre design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Storre without the hardware?

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