WitMotion WT-VL53L0 Laser Distance Sensor, UART TTL / I²C, 3.3–5 V, 3–200 cm Range (20×13×6.2 mm)

Overview

WT-VL53L0 is a compact laser distance sensor based on the VL53L0 ToF engine. It delivers 3–200 cm measuring range with ±3% FS accuracy, supports UART TTL (Serial ASCII) and I²C, and runs from 3.3–5 V. The board integrates an optical cover to suppress stray light, PH1.0-6P socket for quick wiring, and M2 countersunk mounting holes. Baud rate is 2400–921600 bps (115200 default) and the update rate is 0.1–10 Hz (10 Hz default). Size is 20×13×6.2 mm, weight ≈2 g, typical current <36 mA, and operating temperature -20 ~ 70 °C.

Note: Images also show a VL53L1 board (4–400 cm). WT-VL53L0 is the 3–200 cm version; choose VL53L1 if you need up to 4 m.

Key Features

Measurement Modes (typical)

Pinout (PH1.0-6P)

Mechanical Dimensions

• Board: 20 mm × 13 mm × 6.2 mm

• Mounting holes: Ø2 mm, 16 mm center-to-center

• Optical window width: ~12 mm

• Connector length: 10 mm exposed

• Weight: ~2 g (VL53L0 board)

Performance Notes

• Indoor (no external IR) targets with high reflectivity (white ~88%) yield lower error than dark/grey (~17%).

• Use high-accuracy budget for best precision; use high-speed when latency is critical.

Typical Applications

• Doorway/turnstile or security gate object detection

• Robotics obstacle sensing and proximity triggers

• Level/height detection within 2 m

• Compact distance measurement for DIY and embedded systems
