Details
An all-in-one FPV stack that combines the F411 flight controller, 12A 4-in-1 ESC, 5.8GHz analog VTX, and 2.4GHz ELRS RX on a single board for compact builds.
The underside layout keeps the ESC and power sections compact while providing easy access to the Micro USB for setup and firmware work.
Key chips and clearly labeled pads help simplify wiring for camera, video, and control signals on tight micro frames.
A labeled component map makes it easier to locate the MCU, OSD, gyro, VTX, and ELRS areas when troubleshooting or soldering.
Both the 5.8GHz video antenna and the 2.4GHz ELRS antenna are included so the AIO can be installed and bound with minimal extras.
Wiring guidance covers camera power/video, motor outputs, battery leads, and optional external SBUS receiver bridging.
