Atmega32u4: common questions

What microcontroller does the Atmega32u4 use?

The Atmega32u4 is built around the ATmega32U4-A, from the AVR/Arduino family.

How big is the Atmega32u4 PCB?

The Atmega32u4 has 2 copper layers and is 1.6 mm thick.

How many components are on the Atmega32u4?

6 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Atmega32u4 design files?

From the lhondareyte/KiCad-Templates repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Atmega32u4 design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which lhondareyte chose for the repository.

Can I test firmware for the Atmega32u4 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.
