FlightController: common questions

What microcontroller does the FlightController use?

The FlightController is built around the MPU-6050, from the STM32 family.

How big is the FlightController PCB?

The FlightController measures 39 × 39 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FlightController?

42 components, from 29 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 FlightController design files?

From the DiScarlet/FlightController 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 FlightController design in my own project?

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

Can I test firmware for the FlightController 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.
