Scout is an open-source custom quadcopter flight controller firmware that I developed from absolute scratch. The Scout Flight Controller is written in MicroPython and runs on a $4 Raspberry Pi Pico.

Development Tutorial

I'm publicly sharing all that I learned during the three months I spent dreaming about and developing Scout. I wrote a 12-chapter series on how I developed Scout and the hardware requirements. You can find the articles on Medium below:

1. Introducing the Scout Flight Controller
2. Quadcopter Flight Dynamics
3. Capturing Telemetry with a Gyroscope
4. Receiving Pilot Input with an RC Receiver
5. Stabilizing Flight with PID Controllers
6. Controlling Brushless Motors with ESC’s and PWM
7. Setting up the Quadcopter Hardware
8. Full Flight Controller Code & Explanation
9. Taking Flight
10. A Lesson in Persistence
11. Potential Future Improvements
12. Bonus Code

Repository Contents

• The complete source code can be found in the src folder.
• "Bonus code" snippets (code that isn't immediately required by the flight controller software but can be of help for specific tasks anyway) can be found in the bonus_code folder.

Using this Code

I am releasing Scout's full source code under the MIT License. I hope this code can be of use for learning purposes, testing, personal projects, or any other benevolent reason. I do not condone the use of this software for malevolent reasons and do not take responsibility for any direct or indirect consequences. Please explore the skies responsibly.
