CADDXFPV GM3 V2-20 camera gimbal stabilizer for FPV drones

CADDXFPV GM3 V2-20 - is a high-precision 3-axis gimbal stabilizer designed for Walksnail Avatar and Walksnail Ascent cameras with a mounting width of 20mm. It provides effective real-time video stabilization, reduces the impact of vibrations and allows you to smoothly control the camera along the Pitch, Roll and Yaw axes, ensuring a clear and stable image during flight.

The gimbal supports the Head Tracking function, which allows you to control the direction of the camera using compatible Walksnail FPV goggles. For integration with various control systems, support for UART, SBUS, CRSF, PWM and MAVLink protocols is provided, making the GM3 V2-20 compatible with most modern flight controllers.

The model automatically detects the installation position (normal or inverted), supports settings for operating modes, tracking speed and sensitivity via the GimbalSetting software, and is also compatible with ArduPilot, PX4 and INAV autopilots.

Compatibility

The suspension is designed to install Walksnail Avatar and Walksnail Ascent cameras with a mounting width of 20 mm. When using the Walksnail Moonlight camera, a compatible Moonlight VTX video transmitter must be used. It is worth considering that support for the Head Tracking function depends on the VTX version and installed firmware, so it is recommended to check the compatibility of the equipment before installation.

Updates and settings

GM3 V2-20 supports firmware updates via the proprietary GimbalSetting software, which allows you to perform calibration, firmware updates, assign control channels, and change gimbal operation parameters. This provides flexible configuration of the device according to the requirements of a specific FPV platform.
