BetaFPV 20a 2-3s Whoop AIO Serial ELRS 2.4g – MyFPV

Description

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 with plug-and-play support for the DJI O3 system, making it the perfect core for a high-performance cinewhoop or toothpick.

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 & Powerful Performance

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. The integrated 4-in-1 ESC can handle a continuous current of 20A on 2-3S LiPo power and comes flashed with modern Bluejay firmware, which supports bi-directional DShot for RPM filtering. This results in an incredibly smooth and locked-in flight feel with fewer vibrations and less propwash.

Key Features:

• All-in-One Integration: Combines an FC, 20A ESC, and Serial ELRS Receiver on one board for a clean, lightweight, and easy-to-assemble build.
• DJI O3 Ready: A dedicated plug-and-play port and a robust 9V/2A BEC provide simple and reliable power for the DJI O3 Air Unit.
• Serial ELRS 2.4G Receiver: A top-tier, updatable long-range radio link is built-in, no extra receiver needed.
• Bluejay ESC Firmware: Enables RPM filtering on the 20A ESCs for superior propwash handling and smoother motor performance.
• Feature-Rich FC: A powerful F405 MCU, 16MB blackbox, barometer, and 4 free UARTs provide top-tier performance and connectivity.
• Complete Hardware Kit: Comes with all necessary screws, dampers, and adapter cables for a hassle-free installation.
