GPS Module: common questions
What microcontroller does the GPS Module use?
The GPS Module is built around the STM32F103CBT6, from the STM32 family.
How big is the GPS Module?
The GPS Module measures 69.5 × 62.6 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the GPS Module?
61 components, from 39 distinct parts. The full bill of materials is listed on this page.
Where can I download the GPS Module design files?
From the Queens-Rocket-Engineering-Team/Avionics-23-26 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the GPS Module design in my own project?
The repository has no license, so all rights stay with Queens-Rocket-Engineering-Team. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GPS Module 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.
