Gps tracker: common questions

What microcontroller does the Gps tracker use?

The Gps tracker is built around the STM32G070KBTX, from the STM32 family.

How big is the Gps tracker PCB?

The Gps tracker measures 84.9 × 74.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gps tracker?

92 components, from 35 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 Gps tracker design files?

From the candykingdom/gps-tracker 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 Gps tracker design in my own project?

Yes, under the terms of its Apache-2.0 license, which candykingdom chose for the repository.

Can I test firmware for the Gps tracker without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
