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 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Atmega32U4 GPS design files?
From the LeaGuyon/M1 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 GPS design in my own project?
The repository has no license, so all rights stay with LeaGuyon. Use it as a reference, and ask the author before reusing the design.
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.
