Dizzy40: common questions

What microcontroller does the Dizzy40 use?

The Dizzy40 is built around the ATMEGA32U2-A, from the AVR/Arduino family.

How big is the Dizzy40 PCB?

The Dizzy40 measures 229 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dizzy40?

101 components, from 22 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 Dizzy40 design files?

From the str-dst/Dizzy40 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 Dizzy40 design in my own project?

The repository has no license, so all rights stay with str-dst. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dizzy40 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.
