RPLiDAR A3M1 360 2D Laser Scanner Kit, 25 m Range, 16 kHz Sampling, 0.225 Resolution, TTL UART, IEC Class 1

Description

Overview

The RPLIDAR A3M1 360 2D laser scanner kit is a low-cost LIDAR solution from SLAMTEC designed for mapping, localization, and environment modeling. This laser scanner kit captures up to 16000 samples per second with high rotation speed and uses SLAMTECs patented OPTMAG technology for long-term stable operation. It delivers 2D, 360-degree scans with a maximum ranging radius of 25 meters, supports enhanced and outdoor modes for different environments, and meets IEC-60825 Class 1 laser safety.

Key Features

Ranging 16000 times per second

High sample rate (up to 16 kHz) enables fast, accurate map building.

25 m range radius

Collects more environment outline information; distance performance varies by object reflectivity and mode.

Indoor and outdoor availability

Two operating modes: enhanced mode for maximum range and sampling indoors; outdoor mode offers reliable resistance to daylight interference.

360 omnidirectional scanning

Clockwise rotating core generates a full 360 2D point cloud.

Ultra-thin design (~4 cm)

Compact form factor with 41 mm thickness (76 mm x 76 mm x 41 mm), suitable for service robots.

Brushless motor, low noise, non-contact drive

Self-designed brushless motor reduces mechanical friction for smooth, low-noise operation.

OPTMAG original design

Wireless power and optical communication reduce wear versus slip rings, supporting long service life.

IEC-60825 Class 1 laser safety

Low-power infrared laser driven by modulated pulses for eye safety.
