Reliable altitude hold
I integrated this into a custom drone frame for low-altitude holding. The refresh rate is fast enough for stable flight control. Much better than ultrasonic sensors for precision.

Perfect for robotics projects
This sensor is incredibly accurate for its size. I used it on a small rover for obstacle avoidance, and the 4-meter range is more than enough. The included optical cover keeps dust off the lens without affecting performance.

Good for prototyping
We used several of these for a proof-of-concept conveyor belt system. They performed well under controlled conditions. Note that direct sunlight can interfere with readings, which is expected for this technology.

Great value, easy I2C setup
Setup with my Arduino was straightforward using the standard library. It reads consistently well in indoor lighting. Only giving 4 stars because the pin headers were not pre-soldered, but that's minor.

Compact and robust
The form factor is tiny, making it perfect for space-constrained designs. The optical cover feels durable and protects the sensitive components during handling. Highly recommended.

Works exactly as described
First time using a ToF sensor and this module made it easy. The documentation links provided by the seller helped me get started quickly. Measurements are stable and repeatable.
Q: Can this sensor measure through glass?
A: Generally, no. Laser ToF sensors often struggle with transparent materials like glass because the laser passes through or reflects unpredictably. It works best on opaque surfaces.
Q: Does this module work with 5V logic levels directly?
A: No, the VL53L1X operates at 2.6V-3.5V. If you are using a 5V microcontroller like a standard Arduino Uno, you must use a logic level converter or an I2C breakout board with voltage regulation.
Q: Does it come with example code for Raspberry Pi?
A: Yes, the product page includes a link to a GitHub repository with Python examples specifically tailored for Raspberry Pi GPIO usage, as well as C++ libraries for Arduino.
Q: Is the optical cover removable if I need a wider field of view?
A: Yes, the cover can be carefully removed, but please note that doing so exposes the lens to dust and potential damage, and may void the warranty. The default FOV is 25 degrees.
Q: What is the maximum I2C clock speed supported?
A: The sensor supports standard mode (100 kHz) and fast mode (400 kHz). We recommend running at 400 kHz for the fastest possible data update rates.
