BetaFPV 20a 2-3s Whoop AIO | Serial ELRS 2.4g
Build the ultimate lightweight HD FPV drone with the BetaFPV F4 20A AIO V1 Flight Controller. This all-in-one board is a powerhouse of integration, combining a powerful F4 flight controller, a robust 20A 3S ESC, and a Serial ELRS 2.4G receiver onto a single, compact whoop-style board. It is specifically designed for modern HD FPV builds, featuring plug-and-play support for the DJI O3 system, making it the perfect core for a high-performance cinewhoop or toothpick FPV drone kit.
Seamless HD FPV Integration
This AIO is engineered to make building an HD whoop easier than ever. It features a dedicated 6-pin connector for the DJI O3 Air Unit, allowing for a direct, solder-free installation. To ensure a stable, flicker-free video feed, the board includes a robust 9V @ 2A BEC to provide consistent power to the power-hungry DJI O3 system, preventing blackouts during throttle punches.
Built-in ELRS for Long-Range Control
Forget about soldering a separate receiver. This board comes with a Serial ExpressLRS (ELRS) 2.4G receiver integrated, providing a reliable, high-performance, long-range control link right out of the box. Because it’s a serial-based receiver, its firmware can be easily updated via WiFi or Betaflight Passthrough, ensuring you’re always on the latest version of ELRS.
Powerful & Responsive Flight Performance
The integrated 4-in-1 ESC can handle a continuous current of 20A on 2-3S LiPo power, making it perfect for aggressive flying with drones like the Pavo Pico or HX115 SE. It comes flashed with modern Bluejay firmware, which supports bi-directional DShot for RPM filtering in Betaflight. This results in an incredibly smooth and locked-in flight feel with fewer vibrations and propwash.
Builder-Friendly & Feature-Rich
This board is packed with thoughtful features for the builder. It includes a 16MB blackbox for tuning, a barometer for altitude sensing, and four available full-function UARTs for adding other drone parts like GPS. The redesigned layout features larger, more secure solder pads and a relocated USB port for easier access during maintenance and tuning.
