Atmega32: common questions

What microcontroller does the Atmega32 use?

The Atmega32 is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Atmega32 PCB?

The Atmega32 measures 97.5 × 58 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Atmega32?

43 components, from 34 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 Atmega32 design files?

From the George-Emad31/Pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Atmega32 design in my own project?

The repository has no license, so all rights stay with George-Emad31. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Atmega32 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.
