Overview
Flight Controller is an open-source printed circuit board by rishikesh2715, from the rishikesh2715/STM32F7_FC repository on GitHub, published under the MIT licence. It is an 8-layer board of 38.5 × 38.5 mm with 133 parts on 106 nets, routed with 1,094 tracks and 205 vias.
It is built around the AT7456E, STM32F722RET6 and TPS54335ADRCR, with the BMP388, W25Q256JVEIQ and ICM-42688-P among its other parts. Its parts include 47 capacitors, 29 resistors, 13 connectors, 8 ICs and 5 diodes. It belongs with the robots and motor control boards and the STM32 boards of this library.

README
README.mdI am going to be working on a new design of this flight controller.
- Removing AT7456E based analog OSD and CVBS routing.
- Targeting modern digital FPV systems.
- Feel free to recommend any changes you wanna see. Just open an issue.
Hoping to have the new hardware done next month if life chills out.

Questions
How big is the Flight Controller PCB?
It measures 38.5 × 38.5 mm and has 8 copper layers, 1.7 mm thick.
What parts does the Flight Controller use?
133 parts, built around the AT7456E, STM32F722RET6, TPS54335ADRCR and BMP388. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Flight Controller KiCad files?
From the rishikesh2715/STM32F7_FC repository on GitHub, at the commit this page was made from: the board is Flight_Controller.kicad_pcb and its schematic FC_Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight Controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
