Seeed Studio RPLiDAR A3M1 360 Degree Laser Scanner Kit
Seeed Studio RPLiDAR A3M1 360 Degree Laser Scanner Kit is a next-generation, cost-effective 2D laser scanning solution developed by SLAMTEC. It delivers up to 16,000 samples per second with high rotational speed, ensuring precise and reliable data collection. Equipped with SLAMTEC’s patented OPTMAG technology, this scanner overcomes the lifespan limitations of traditional LIDAR systems, enabling stable long-term operation for both indoor and outdoor mapping and localization.
The system performs continuous 360-degree scans within a 25-meter range, generating detailed 2D point cloud data that can be applied to environment modeling, robot navigation, and SLAM-based mapping. Compared with other RPLIDAR series, the A3M1 offers more stable performance when detecting objects at long distances, under direct sunlight, or with alternating black and white surfaces, making it ideal for outdoor LoRa-based robotics and consumer applications.
The RPLIDAR A3M1 supports two operating modes: Enhanced Mode and Outdoor Mode. Enhanced Mode maximizes range and sampling rate for optimal indoor mapping performance, while Outdoor Mode provides stronger resistance to daylight interference, ensuring reliable operation in challenging outdoor environments.
The typical scanning frequency is 10Hz (600 rpm), adjustable between 5–20Hz depending on requirements. At 10Hz, the sampling rate reaches 16kHz with an angular resolution of 0.225°, delivering high-precision mapping results. Each unit undergoes strict factory testing to meet IEC-60825 Class 1 eye-safety standards, ensuring safe use around humans and pets.
Features
■ High-Speed Sampling
With an improved optical design and algorithm system, the RPLIDAR A3M1 achieves 16,000 samples per second, enabling robots and autonomous systems to build maps quickly and accurately.

■ Extended 25-Meter Range
Optimized algorithms increase the ranging radius to 25 meters, allowing more comprehensive environmental data collection for networked robotics and SLAM applications.
■ Indoor and Outdoor Modes
The A3M1 alternates between Enhanced Mode and Outdoor Mode. Enhanced Mode maximizes mapping performance indoors, while Outdoor Mode ensures stable detection under sunlight and across varied surfaces.
■ 360-Degree Omnidirectional Scanning
The core scanning system rotates clockwise to perform full 360-degree scans, generating accurate environmental outlines for autonomous navigation.
■ Compact 4-Centimeter Design
With a slim 4 cm profile, the RPLIDAR A3M1 maintains exceptional performance in a compact form factor, making it suitable for service robots and mobile platforms.
■ Brushless Motor and Non-Contact Drive
Unlike traditional belt-driven systems, the A3M1 uses a self-designed brushless motor to minimize mechanical friction, resulting in smooth, low-noise operation.
■ OPTMAG Technology for Extended Lifespan
By integrating wireless power and optical communication, SLAMTEC’s OPTMAG design eliminates mechanical wear issues common in slip-ring systems, extending operational life to five years or more.
■ Class 1 Laser Safety
The RPLIDAR A3M1 employs a low-power infrared laser with modulated pulses, ensuring compliance with Class 1 safety standards for safe use in consumer and industrial environments.

Important Notice:
- Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Long Beach warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
- Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Long Beach warehouse first (typically taking 5-10 business days) before dispatching them to you.
- Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.
3. International Warehouse
Our products are stored in our Munich, Long Beach, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.
