Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The RPLIDAR A1 is a 360° omnidirectional laser ranging sensor based on laser triangulation. It scans up to 12 m and provides 2D point clouds for mapping, localization, and object detection.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL22342 WSAL22342 – Slamtec RPLIDAR A1 Laser Ranging Sensor, 360° Omnidirectional Lidar]<br /> <br /> == Technical overview ==<br /> * Principle: laser triangulation; 360° scan range<br /> * Typical distance range: 0.15–12 m<br /> * Measurement frequency: 8000 Hz (scan rate 5.5 Hz at 1450 points per round, configurable up to 10 Hz)<br /> * Angular resolution: ≤ 1°<br /> * Communication: UART @ 115200 bps, 8N1<br /> * Power: 5 V, typical 100 mA, ~0.5 W<br /> * Mechanical dimensions: 96.8 × 70.3 × 55 mm<br /> * Operating temperature: 0 °C to 40 °C<br /> * Accuracy: 1% (≤3 m), 2% (3–5 m), 2.5% (5–12 m) of actual distance<br /> <br /> == Notes and version constraints ==<br /> * The stated 115200 bps applies to the radar itself; the adapter board defaults to 57600 bps – verify before connecting.<br /> * The A1M8 RX input logic is current-controlled; the pin voltage must be at least 1.6 V for reliable signal detection.<br /> * Exact firmware version and compatibility with specific microcontrollers (e.g., Arduino) are not fully specified in the source; verify pinout and level values before wiring.<br /> * The driver files (CP210x_Driver.zip, frame_grabber.zip) are only available via the Waveshare page; their integrity should be verified before installation.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/RPLIDAR_A1 RPLIDAR A1 - Waveshare Wiki]<br /> * Source revision: 81728<br /> * Captured: 2026-09-03T03:52:18+00:00<br /> * SHA-256: &lt;code&gt;6af8ce5a1c6729769fe6c801ce265a1c486df775ba94f8c52f4353a58d8d0423&lt;/code&gt;</div>
