Board-Stupid: common questions

What microcontroller does the Board-Stupid use?

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

How big is the Board-Stupid?

The Board-Stupid measures 68.6 × 53.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Board-Stupid?

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

Where can I download the Board-Stupid design files?

From the reading-hackspace/Board-Stupid repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Board-Stupid design in my own project?

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

Can I test firmware for the Board-Stupid 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.
