Details
Browse the SLAM LiDAR series and choose a model that matches your range, speed, and environment requirements.
Additional LiDAR options are available if you need a different sensing profile than the RPLIDAR SLAM series.
For compact builds, compare footprint and interface needs alongside the RPLIDAR models.
RPLIDAR C1 uses TOF ranging for stable distance measurement with a compact housing option.
RPLIDAR A1 is a triangulation-based choice for ROS learning, mapping, and navigation projects.
If your platform requires different update rates or protection levels, review alternative sensor cards before checkout.
S2/S2L models are TOF-based options designed for higher performance mapping and navigation.
Handheld mapping is supported with compatible setups for SLAM C1 and ROS2 development workflows.
The SLAM series includes C1, A1/A1 high-speed, A2, S2/S2L, and S3 to cover different ranging principles and application needs.
Select the model that fits your project—triangulation (A1/A2) or TOF (C1, S2/S2L, S3)—then integrate via UART and ROS.
A side-by-side parameter table helps compare scan rate, range, interface speed, and typical use cases across the series.
Match the sensor to your operating environment—indoor, outdoor, and strong-light scenarios vary by model.
The A1 high-speed version adds stepless scan-frequency adjustment and a simpler Type‑C connection path for development.
Triangulation and TOF ranging behave differently across surface types and distances; choose the principle that suits your use case.
TOF-based models (C1, S2/S2L, S3) are designed for consistent ranging performance at longer distances.
Use the SLAM series with common development platforms including Raspberry Pi, Jetson, and PC-based robotics stacks.
