README
README.mdUltraHawk
A custom fully autonomous drone designed to run custom firmware on a fully custom flight controller. It is capable of autonomously navigating to waypoints.
Ultrahawk utilizes a fully custom PCB made out of SMT components that can be manufactured via a pick-and-place machine, or manually soldered on via hot plate.
You may find KiCAD files in the pcb directory, along with the production folder including a .zip file for easy export to PCB services as JLCPCB and PCBWay.
Components may be found in the bom.csv file containing the LCSC part numbers for each part.
UltraHawk also uses a custom frame that is designed to be 3D printed. CAD files for this can be found in the CAD folder as .step files.
The drone can then be assembled using the rest of the parts such as motors, esc's, and batteries, all of which can be found in the bom.csv file.
Perliminary firmware for the project may also be found in the firmware directory.
See bom.csv for full price breakdown. See JOURNAL.md for full work log.

Questions
How big is the UltraHawk PCB?
It measures 50 × 87 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UltraHawk use?
81 parts, built around the BMP581, LIS3MDL, TPS565208DDC and AO3400A. 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 UltraHawk KiCad files?
From the InSynchronous/UltraHawk repository on GitHub, at the commit this page was made from: the board is pcb/UltraHawk.kicad_pcb and its schematic pcb/UltraHawk.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UltraHawk 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).
