Easy to setup

Documentation could be better but once configured via the serial terminal, it works like a charm. Voltage requirements are standard 5V.

Perfect for ROS2 Robotics

Integrated smoothly with my ROS2 navigation stack. The serial output is stable and the range is accurate within specs. Great for obstacle avoidance.

Good accuracy, slight lag

Accuracy is spot on for indoor use. Noticed a tiny bit of lag at max frequency but overall solid performance for the price point.

Solid single-point sensor

Does exactly what it says. Not a scanning LiDAR but perfect for specific distance monitoring tasks. Build quality is decent.

Reliable for AGV

Using this on our automated guided vehicle project. Consistent readings even in varying light conditions. Highly recommend for industrial prototypes.

A: The module comes with a 4-pin GH1.25mm connector cable. USB adapters are sold separately.

Q: Can this be used outdoors in sunlight?

A: It works best indoors. Direct sunlight may interfere with the TOF measurement accuracy beyond 5 meters.

Q: What is the power consumption?
