Stubby: common questions

What microcontroller does the Stubby use?

The Stubby is built around the ATMEGA1284-A, from the AVR/Arduino family.

How big is the Stubby PCB?

The Stubby measures 49.5 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stubby?

62 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stubby design files?

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

Can I use the Stubby design in my own project?

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

Can I test firmware for the Stubby 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.
