README
README.mdpcb_quadcopter
An open-source PCB multirotor project, development in progress. The intent is to make an affordable, simple and customizable quadcopter that can be built and used by anyone.
Inspiration
So, I have seen some interesting projects online and decided to try developing a variation. Here are some of the references that inspired me into making my own:
- Arduino PCB quadcopter - ElecttoNOOBS
- ArduBee, a Ready-To-Fly Micro drone for Education and Swarming
- Microhawk at Outcast Dronework - Rotor Riot
- MultiWii
- OpenFC Open Hardware Flight Controller - DroneMesh
- FeatherWing quadcopter
Specifications
Here are some of the specifications that I want to follow for this project. They are open to changes:
- PCB Frame containing all of the electronics and components
- STM32 microcontroller able to run BetaFlight
- 7mm brushed motors
- 2" Propellers
- Micro RF SBUS receiver
- 18650 Li-Ion batteries
Future implementations/extras
Theese are some features that are cool but aren't included in the base project (yet, hopefully):
- FPV camera and VTX
- SD card for camera footage
- RPi 0 support
- Ardupilot support

Questions
How big is the Schematics PCB?
It measures 190 × 190 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schematics use?
56 parts, built around the MPU-6000, BAT54C and BC817. 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 Schematics KiCad files?
From the joaom98/pcb_quadcopter repository on GitHub, at the commit this page was made from: the board is schematics/main_board/main_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schematics design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
