Learn it. Build it. Change it. Create your own.
Open firmware, open reference hardware, and a free companion app for enthusiasts, students, educators, Makers, developers, and engineers who want to learn, experiment, and build ESP-powered drones.
A practical flight foundation for learning, hands-on experimentation, custom hardware, and ideas that can grow further.
Everything between an idea and the air.
ESPFlight keeps the core pieces together so you can spend less time assembling unrelated tools and more time learning how a drone works, experimenting with it, and developing your own ideas.
Open firmware
A focused flight-control stack for ESP-powered drones: stabilization, telemetry, safety logic, assisted flight and a network control protocol.
Open hardware
Start from a reference board, study how it works, then adapt the layout and form factor for your own build.
Companion app
One polished control surface for flying, configuration and telemetry across ESPFlight-compatible drones.
A working foundation should be a starting point, not a cage.
A small flying platform has to solve flight control, hardware integration, telemetry, configuration, and safety together. ESPFlight keeps those foundations coherent so you can understand and change them instead of rebuilding the same groundwork from zero.
Read the philosophyESPFlight is not here to define what everyone builds. It is here to give people a foundation they can learn from and make their own.
Licensing is component-specific: Firmware uses MIT, Hardware Reference uses CERN-OHL-P-2.0, documentation uses CC BY 4.0, and the Application is proprietary. ESPFlight name and logo rights remain separate.
Your board. Your shape. Your idea.
ESPFlight is infrastructure, not a product shape you have to copy. Start with the reference design, understand it, change what your project needs, and make the result your own.
One control surface for the whole ecosystem.
Fly, tune, inspect telemetry and manage your drone from a companion experience built around ESPFlight from day one.
Choose your starting point. Keep your freedom.
I want to understand and build a drone.
Follow the reference stack from components to a controllable drone while learning what each layer does.
Start building MAKER / DEVELOPERI want to create my own board.
Study and adapt the reference design to your dimensions, components, frame, and technical goals.
Explore hardware INDEPENDENT KITI want to take my project further.
Turn a validated design into a kit or product under your own independent brand, and choose to sell it when you are ready.
For MakersIf there is a name on the box, it stays yours.
If you choose to turn a project into a kit or product, your own identity stays in front. ESPFlight remains the underlying platform, and reserved brand wording such as “Powered by ESPFlight” follows the Brand Policy.
