ButaBoard: common questions

What microcontroller does the ButaBoard use?

The ButaBoard is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the ButaBoard PCB?

The ButaBoard measures 71.6 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ButaBoard?

79 components, from 46 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 ButaBoard design files?

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

Can I use the ButaBoard design in my own project?

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

Can I test firmware for the ButaBoard 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.
