PROMETHEUS: common questions
What microcontroller does the PROMETHEUS use?
The PROMETHEUS is built around the STM32H743VIT6, from the STM32 family.
How big is the PROMETHEUS PCB?
The PROMETHEUS measures 115 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PROMETHEUS?
259 components, from 148 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 PROMETHEUS 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 PROMETHEUS 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 PROMETHEUS 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.
