FlightComputer: common questions
What microcontroller does the FlightComputer use?
The FlightComputer is built around the STM32F103VCT6, from the STM32 family.
How big is the FlightComputer PCB?
The FlightComputer measures 90 × 90 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the FlightComputer?
78 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the FlightComputer design files?
From the jbrown3859/EE175-SeniorDesign repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FlightComputer design in my own project?
The repository has no license, so all rights stay with jbrown3859. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FlightComputer 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.
