Done — I cleaned up the Betaflight Firmware page with proper Markdown headings, bullet lists, numbered setup steps, a fenced CLI code block, and a safety/bring-up checklist.
FPV Camera — a small onboard camera that provides real-time video to the pilot for first-person view (FPV) control.
XT60 Power Connector — the main battery connector; handles high current and ensures a secure power connection.
Flight Controller — the drone’s “brain” (STM32F405RGT6): reads sensors, runs stabilization/control algorithms, and outputs motor commands.
4× Electronic Speed Controllers (ESCs) — convert control signals into three‑phase power for the motors; manage motor timing, current sensing, and protections.
Video Transmitter (VTX) — sends the FPV video feed to ground receivers or goggles; includes antenna output and power/power‑level settings.
Motors & Propellers — the drone’s “muscles”: brushless motors spin the propellers to generate lift and thrust for maneuvering.
