WitMotion WT-VL53L0 Laser Distance Sensor, UART TTL / IC, 3.35 V, 3200 cm Range (20136.2 mm)

Overview

WT-VL53L0 is a compact laser distance sensor based on the VL53L0 ToF engine. It delivers 3200 cm measuring range with 3% FS accuracy, supports UART TTL (Serial ASCII) and IC, and runs from 3.35 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 2400921600 bps (115200 default) and the update rate is 0.110 Hz (10 Hz default). Size is 20136.2 mm, weight 2 g, typical current <36 mA, and operating temperature -20 ~ 70 C.

Note: Images also show a VL53L1 board (4400 cm). WT-VL53L0 is the 3200 cm version; choose VL53L1 if you need up to 4 m.

Measurement Modes (typical)

Mode	Distance budget (approx.)	Typical performance	Use case
Default	30 ms	~1.2 m, standard accuracy	General detection
High-accuracy	200 ms	~1.2 m, 3%	Precision measurement
Long-distance	33 ms	2 m, standard accuracy	Low-IR / darker scenes
High-speed	20 ms	~1.2 m, 5%	Fast response

Pinout (PH1.0-6P)

No.	Name	Description
1	VCC	Power input 3.35.0 V
2	RXD	UART receive (TTL level; do not connect directly to RS-232). Connect to MCU TXD
3	TXD	UART transmit (TTL level; do not connect directly to RS-232). Connect to MCU RXD
4	SCL	IC clock (valid when module is in IC mode)
5	SDA	IC data (valid when module is in IC mode)
6	GND	Ground

Mechanical Dimensions

• Board: 20 mm 13 mm 6.2 mm

• Mounting holes: 2 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
