0.4: common questions

What microcontroller does the 0.4 use?

The 0.4 is built around the PREC040SAAN-RC, from the AVR/Arduino family.

How big is the 0.4 PCB?

The 0.4 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 0.4?

142 components, from 45 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 0.4 design files?

From the speeduino/Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 0.4 design in my own project?

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

Can I test firmware for the 0.4 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.
