Flight Data Recorder: common questions
What microcontroller does the Flight Data Recorder use?
The Flight Data Recorder is built around the INA228, from the STM32 family.
How big is the Flight Data Recorder PCB?
The Flight Data Recorder measures 50 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Flight Data Recorder?
89 components, from 60 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 Flight Data Recorder design files?
From the EPFLRocketTeam/2026_C_AV_HARDWARE 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 Flight Data Recorder design in my own project?
The repository has no license, so all rights stay with EPFLRocketTeam. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Flight Data Recorder 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.
