Yunshis MVR3ECD 30m ToF 940nm UART/TTL Laser Ranging Module for Robots & AGV, up to 200Hz

Overview

Yunshis MVR3ECD is a 30 m laser ranging module designed for medium-range distance measurement. It uses ToF (Time-of-Flight) technology with a 940 nm IR VCSEL light source, and is intended for easy integration via UART/TTL serial communication. The module supports anti-sunlight interference and provides centimeter-level accuracy for indoor and outdoor ranging requirements from 0.3 to 30 meters.

Key Features

• Measurement distance range: 0.3 to 30 m
• Anti-sunlight interference
• High-speed output: up to 200 Hz output frequency (measurement frequency adjustable at 10/20/50/100/200 Hz)
• UART/TTL serial communication
• UART output data formats: HEX and ASCII
• Supports distance threshold configuration
• Supports serial wake-up function
• PCBA + lens bracket structure; compact size for convenient integration
• Reserved mounting holes at four corners for stable installation and repeatable fixation

Details

A compact 30 m ToF ranging module designed for reliable indoor/outdoor distance measurement with UART/TTL integration.

High-speed ranging data is available up to 200 Hz, with centimeter-level performance for medium-range robotics sensing.

Built around a 940 nm VCSEL ToF sensor, MVR3ECD targets multi-scenario robots and AGV platforms that need stable ranging.

Anti-sunlight interference, serial wake-up, and reserved mounting holes support straightforward installation and repeatable alignment.

Common uses include obstacle avoidance, distance threshold triggers, and automated measurement workflows in mobile robots.

Mechanical drawing helps confirm fit and mounting clearances; dimensions are provided in millimeters with Pin 1 (VCC) identified.
