Flight Controller: common questions

What microcontroller does the Flight Controller use?

The Flight Controller is built around the ESP32-S3-WROOM-1U-N4R8, from the ESP32 family.

How big is the Flight Controller PCB?

The Flight Controller measures 102 × 41.1 mm, has 6 copper layers and is 1.5584 mm thick.

How many components are on the Flight Controller?

139 components, from 63 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 C-yue28/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 C-yue28. 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 ESP32 firmware against it before you order a PCB.
