Stormduino: common questions

What microcontroller does the Stormduino use?

The Stormduino is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Stormduino PCB?

The Stormduino measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stormduino?

45 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stormduino design files?

From the Chromico/stormduino repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Stormduino design in my own project?

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

Can I test firmware for the Stormduino 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.
