Flight-Controller design files

The KiCad project lives in the Mithilessh2010/Flight-Controller repository on GitHub; these links point at the commit this page was built from.

Flight-Controller: common questions

What microcontroller does the Flight-Controller use?

The Flight-Controller is built around the STM32F722RETX, from the STM32 family.

How big is the Flight-Controller PCB?

The Flight-Controller measures 40 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Flight-Controller?

79 components, from 37 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-Controller design files?

From the Mithilessh2010/Flight-Controller 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-Controller design in my own project?

The repository has no license, so all rights stay with Mithilessh2010. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Flight-Controller 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.
