(🚧) A "Jack of all trades" custom flight controller board. With support for both power and control and the ability for custom firmware

I am currently trying to build my own drone from scratch, and slowly replace every component with my own, from creating fully custom PCBs for the flight controller or ESCs, to making a 3D printed drone chassis etc etc. And this is the fully fledged, multi functional, cool-looking flight controller. I present to you:

For one of my biggest projects yet I designed a jack of all trades custom flight controller board. It also comes with custom firmware, or if possible compatibility with betaflight or other FC firmware out there. At it's core are two PCBs arranged in a stackup with the "top" and…

Sabre-Integrated flight controller: common questions

What microcontroller does the Sabre-Integrated flight controller use?

The Sabre-Integrated flight controller is built around the STM32F765VGTX, from the STM32 family.

How big is the Sabre-Integrated flight controller PCB?

The Sabre-Integrated flight controller measures 60 × 137.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sabre-Integrated flight controller?

260 components, from 94 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 Sabre-Integrated flight controller design files?

Can I use the Sabre-Integrated flight controller design in my own project?

Yes, under the terms of its GPL-3.0 license, which CircuitGuy943 chose for the repository.

Can I test firmware for the Sabre-Integrated 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.
