Easy to use library support
I was worried about the integration complexity, but there are plenty of open-source libraries available. It connected instantly to my ESP32 and started providing accurate data within minutes.

Perfect for my robotics project
This ToF sensor is incredibly small and lightweight, making it ideal for my drone obstacle avoidance system. The readings are consistent and the UART interface was easy to integrate with my microcontroller.

Compact and efficient
Exactly as described: small size and low cost. It fits perfectly into tight spaces on my custom PCB. The only downside is the short cable included, but that's a minor issue.

Best bang for your buck
I have tried several ranging modules, and this one offers the best balance between price and performance. The accuracy is impressive for a module of this size and cost.

Good value but needs calibration
Great low-cost module for general distance sensing. I noticed slight variations at the maximum range, but after calibrating in my specific environment, it works perfectly for indoor mapping.

Reliable and fast
The sampling rate is sufficient for real-time applications. I've tested it in various lighting conditions, and the time-of-flight technology holds up much better than ultrasonic sensors.
Q: Does this module work outdoors in direct sunlight?
A: While the sensor functions outdoors, direct intense sunlight can affect the maximum range and accuracy. It performs best in shaded outdoor areas or indoor environments.
Q: What is the pinout configuration for the UART interface?
A: The standard pinout is VCC, GND, TX, and RX. Please refer to the datasheet included in the download section for the specific pin ordering on your batch.
Q: Can I connect multiple sensors to one microcontroller?
A: Yes, if you use the I2C interface, you can connect multiple units provided they have configurable addresses. For UART, you would need separate hardware serial ports or a software multiplexer.
Q: Is the laser safe for human eyes?
A: Yes, this module uses a Class 1 laser, which is considered safe for human eyes under normal operating conditions according to international safety standards.
Q: Does it come with a mounting bracket?
A: The module does not include a dedicated mounting bracket, but it features two standard mounting holes with a 2mm diameter for easy custom integration.
