Stratosphere-FC: common questions

What microcontroller does the Stratosphere-FC use?

The Stratosphere-FC is built around the STM32F405RGTx, from the STM32 family.

How big is the Stratosphere-FC PCB?

The Stratosphere-FC measures 37.6 × 30.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stratosphere-FC?

49 components, from 31 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 Stratosphere-FC design files?

From the esb8/Stratosphere-Avionics 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 Stratosphere-FC design in my own project?

The repository has no license, so all rights stay with esb8. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Stratosphere-FC 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.
