Compatible with Raspberry Pi, Arduino, and ESP32 via UART\/I2C interfaces, its \u003cstrong\u003eultra-compact design (19×12×10.3mm, 1 gram) \u003c\/strong\u003eand multi-protocol support make it ideal for robot and drone obstacle avoidance and navigation, robotics, IoT, and industrial automation.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eUltra-Lightweight \u0026amp; Miniaturized Design\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eWeighing 1g with dimensions of 19×12×10.3mm, the sensor is one of the smallest and lightest dToF solutions on the market. Its 19mm³ footprint allows direct integration into micro-drones, wearable devices, or robotic joints without compromising payload capacity or mobility. The design eliminates traditional bulky optics, enabling deployment in space-critical applications like micro-drone obstacle avoidance or smartwatch gesture control.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHigh-Speed Dynamic Ranging\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eWith a 50Hz refresh rate, the sensor delivers real-time distance updates, critical for applications requiring rapid response, such as drone obstacle avoidance or industrial conveyor belt monitoring. The narrow 2-3° field of view minimizes interference from ambient light and background noise, ensuring stable performance in both indoor and outdoor settings.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eRobust Anti-Interference Capability\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe sensor operates reliably under 100,000 lux ambient light (equivalent to direct sunlight), making it suitable for outdoor traffic monitoring or construction sites.
