Overview

Redfox A3 is an F722-based AIO flight controller with integrated 35A/45A BLHeli_32 4-in-1 ESC, designed for 2 to 3.5-inch FPV drones such as DollyFly25. It features an external USB-C Type-C adapter board for convenient setup, an onboard DJI 6-pin interface for digital video systems, and a 5V 2.5A BEC for powering peripherals.

Key Features

  • MCU: STM32F722 for fast, real-time flight control response
  • Integrated BLHeli_32 35A/45A ESC with up to 128 kHz PWM frequency support
  • DJI 6-pin interface for direct connection to DJI digital video transmission systems
  • External USB-C port module: SH1.0 5-pin to Type-C, with boot button
  • UART: 6 sets (UART1–UART6), including UART1/2/3 for Digital VTX / SBUS receiver, UART4/5 for ESC telemetry
  • Onboard OSD (AT7456E) and built-in barometer
  • Supports external buzzer and external LED
  • 5V 2.5A BEC output for peripherals (GPS, LED, buzzer, etc.)
