From the project

QRET Avionics hardware, firmware, and documentation for 2023 to 2025.

Note that the 1.0A revision of this module has the CP2102's reset pin incorrectly pulled-down (this required a bodge wire to pull it high).

Sensors Module: common questions

What microcontroller does the Sensors Module use?

The Sensors Module is built around the STM32F103CBT6, from the STM32 family.

How big is the Sensors Module?

The Sensors Module measures 69.5 × 62.6 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Sensors Module?

184 components, from 59 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sensors 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 Sensors 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 Sensors 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.
