The Slamtec A1M8 RPLIDAR A1 is a compact 360-degree 2D LiDAR sensor for robot mapping, localization, obstacle detection, and indoor navigation projects. It uses Slamtec's laser triangulation ranging system with high-speed vision acquisition hardware to output distance and angle data for 2D point-cloud perception. With an 8K sampling frequency, a 0.15 m to 12 m measuring range, and a configurable scan rate, the A1M8 gives mobile robots a practical sensing layer for SLAM, education, prototyping, and service robot development. Its 5 V system voltage and UART serial output make it suitable for embedded robotics platforms and host-computer development workflows. Features 360-degree omnidirectional scanning - The rotating scan core captures a full planar view of the surrounding environment for mapping and localization. 8K sampling frequency - Measures distance data at up to 8000 samples per second for responsive 2D perception. 0.15 m to 12 m measuring range - Covers short-range indoor navigation and room-scale mapping applications. Configurable scan rate - Supports a typical 5.5 Hz scan rate and can be configured up to 10 Hz, with scan rate adjustment through motor control. Laser triangulation ranging - Uses Slamtec's high-speed vision acquisition and processing hardware to generate distance and angle data. OPTMAG design - Uses Slamtec's optical-magnetic design to reduce the wear limitations associated with traditional slip-ring transfer. Robot-friendly integration - Provides UART serial output at 3.3 V logic level and supports USB-based development connection options.
