Atmega32U4 GPS: common questions
What microcontroller does the Atmega32U4 GPS use?
The Atmega32U4 GPS is built around the ATmega32U4-A, from the AVR/Arduino family.
How big is the Atmega32U4 GPS PCB?
The Atmega32U4 GPS measures 40.5 × 35 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Atmega32U4 GPS?
30 components, from 21 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 Atmega32U4 GPS design files?
From the Pauloux/Projet-ATCE 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 Atmega32U4 GPS design in my own project?
Yes, under the terms of its GPL-3.0 license, which Pauloux chose for the repository.
Can I test firmware for the Atmega32U4 GPS 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.
