Beetje 32U4 Blok: common questions

What microcontroller does the Beetje 32U4 Blok use?

The Beetje 32U4 Blok is built around the ATMEGA32U4-AUR, from the AVR/Arduino family.

How big is the Beetje 32U4 Blok PCB?

The Beetje 32U4 Blok measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Beetje 32U4 Blok?

6 components, from 6 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 Beetje 32U4 Blok design files?

From the aspro648/Leonardo repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Beetje 32U4 Blok design in my own project?

The repository has no license, so all rights stay with aspro648. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Beetje 32U4 Blok 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.
