Flight-Controller: common questions

What microcontroller does the Flight-Controller use?

The Flight-Controller is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Flight-Controller PCB?

The Flight-Controller measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Flight-Controller?

74 components, from 42 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 MarkSherstan/Drone repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Flight-Controller design in my own project?

Yes, under the terms of its MIT license, which MarkSherstan chose for the repository.

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 AVR/Arduino firmware against it before you order a PCB.
