Overview
This FPV stack combo pairs the Hobbywing XRotor Convertible F7 flight controller with a 65A 30x30mm 4-in-1 ESC for multirotor quadcopters. The FC uses an STM32F722 MCU with an ICM20602 six-axis motion sensor, supports bidirectional DShot digital throttle communication, and includes built-in OSD plus onboard Flash memory for flight log recording. The ESC runs open-source AM32 firmware on a 32-bit ARM F4 MCU (120 MHz) and supports variable PWM refresh rate from 48 kHz to 96 kHz.
Key Features
- STM32F722-based F7 flight controller with ICM20602 six-axis motion sensor
- Bidirectional DShot digital throttle communication
- Built-in OSD; OSD parameters adjustable in FC setup software and via radio
- On-board Flash memory for recording and storing flight logs
- DJI image transmission system port with flat cable for plug-and-play installation (no soldering required for that connection)
- On-board 5V & 12V dual BEC circuit (12V current rating not specified)
- On-board Pit Switch module (radio control after configuration in FC parameter software)
- Supports firmware and configuration tools including Betaflight and Cleanflight (also listed: Butterflight, INAV)
- AM32 open-source ESC firmware; 32-bit ARM F4 MCU running at 120 MHz
- Variable PWM refresh rate support: 48 kHz to 96 kHz (dynamic auto-adjustment stated)
- ESC built-in voltmeter for real-time voltage and current monitoring by the flight controller
- Shock-absorbing mounting hole design; FC mounting hole spacing listed as 30 x 30 mm and 20 x 20 mm

Details

The XRotor AM32 FPV stack combines two compact boards with clearly labeled pads, a plug connector, and soft mounting grommets for a clean 30x30 build.

A 120MHz operating frequency and variable PWM refresh rate from 48kHz to 96kHz support responsive ESC control.

The XRotor F7 flight controller uses an STM32F722 MCU and ICM20602 sensor with bidirectional DShot support and an integrated OSD for setup.

The XRotor F7 flight controller includes a dedicated DJI image transmission connector to simplify plug-and-play wiring without soldering.

The XRotor F7 flight controller includes an on-board 5V and 12V dual BEC circuit for powering supported FPV and LED accessories.

The XRotor F7 flight controller includes an on-board Pit Switch module that can toggle the VTx on or off via radio after setup in FC software.

The XRotor F7 flight controller is designed to work with popular FPV firmware like Betaflight, Cleanflight, Butterflight, and INAV for easier setup and tuning.

The XRotor F7 flight controller stack uses soft-mount grommets and supports 30x30mm and 20x20mm mounting patterns for flexible installs.
