FlightComputer: common questions
What microcontroller does the FlightComputer use?
The FlightComputer is built around the STM32H745IIT6, from the STM32 family.
How big is the FlightComputer PCB?
The FlightComputer measures 148 × 102 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the FlightComputer?
409 components, from 92 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 FlightComputer design files?
From the akkdong/FlightComputer repository on GitHub, which has the KiCad layout and the BOM; 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 akkdong. 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.
