What It Solves
Need open-source firmware to run on flight controller hardware for UAV stabilization and control.
Primary use cases
- Running open-source flight controller firmware on UAV flight controller boards
Secondary use cases
- Customizing flight control software
When to Use
Consider when
- Require GPL-3.0 licensed flight controller firmware (license inferred)
Verify before adopting
- License inferred from GitHub API spdx_id; verify in repo LICENSE
- No hardware targets listed; verify board support before adoption

Adoption Checklist
- Needs verification License inferred from GitHub API spdx_id; verify in repo LICENSE
- Needs verification No hardware targets listed; verify board support before adoption
Each check stays "needs verification" until an official source confirms it; unconfirmed items are never marked verified.
