BETAFPV Cube 2-4S Brushless AIO

„Cube Brushless Flight Controller is a new BETAFPV 2-4S 3-in-1 AIO flight controller designed specifically for Pavo-type digital whoop drones. It integrates a powerful STM32G473 168 MHz processor, 30 A ESC and Serial ELRS 2.4 GHz receiver. The updated 30 A ESC with 2 oz copper layer ensures better heat dissipation and sufficient power for aggressive freestyle flight, while the powerful processor ensures precise, smooth control.

Features:

• „3-in-1 integration: STM32G473 processor, 2-4S 30 A ESC and Serial ELRS 2.4 GHz receiver integrated into one compact board;
• 30A ESC: Supports 30A continuous current, and the 2oz copper layer ensures reliable performance and better heat dissipation;
• Powerful processor: STM32G473 operating at 168 MHz ensures high computing power and fast and precise drone control;
• Optimized for digital VTX: compact and cost-effective solution for digital HD whoop drones;

Designed specifically for digital VTX whoop drones, the Cube 3IN1 FC combines an STM32G473 processor, a 2-4S 30 A ESC, and a Serial ELRS 2.4 GHz receiver on a single compact board, making drone assembly easier. The 168 MHz STM32G473 processor ensures fast and precise control, while additional serial ports allow you to connect a GPS module or other external devices.

„The Cube FC board uses a 2 oz thick copper layer for improved heat dissipation and current flow. The updated 2-4S Bluejay ESC delivers 30A of continuous current, compared to 20A in the F405 controllers, reliably powering Pavo whoop drones even during aggressive freestyle maneuvers.
