Key Features

30ms Extremely Fast Response

With an integrated 32-bit processor and dual filtering (hardware + software), the SUI04 provides extremely fast and accurate detection (30ms response), solving the delay problems common to many other ultrasonic modules. Its ideal for use in precision applications such as agricultural drones and beginner drone training, helping avoid obstacles in real time.

Compatible flight controllers: RadioLink CrossFlight, CrossRace, PIXHAWK, Mini Pix, TURBO PiX (requires Copter V3.5.7 firmware upgrade).

60 Beam Angle, Zero Fade Area

Each SUI04 sensor transmits and receives within a 60 cone, enabling complete coverage with no blind spots. Used in conjunction with six units and an I2C expansion board, it allows real-time, all-directional detection (forward, backward, left, right, upward, downward).

High Precision of 0.4cm

The SUI04 boasts a detection accuracy of 0.4cm, ensuring that even small and near-range obstacles are detected with high reliability, supporting safer and smoother flight.

Compact & Lightweight Design

Measuring only 202219mm and weighing just 8g (with wires), the SUI04 is optimized for drones with limited payload capacity. The all-in-one transmitter-receiver module makes installation on small airframes easyeven for 210mm-class FPV racers.

Specifications

Connection and Integration

The SUI04 can be connected to the Mini Pix or other supported controllers via an I2C expansion board. This enables 6-directional obstacle avoidance and supports precise altitude holding in real-time.

Training & Outdoor Safety

Designed with education and training in mind, the SUI04 allows beginners to avoid hitting the ground or ceiling while adjusting throttle. This makes it ideal for flight instruction environments, enhancing safety for both users and teaching gear.
