RPLidar A1 360° Laser Scanner for Robotics & SLAM - Compoden
RPLidar A1 360-Degree Laser Scanner for Robotics & SLAM
The RPLidar A1 is a 360-degree 2D laser scanner from SLAMTEC, designed for real-time mapping and simultaneous localization and mapping (SLAM) in robotics projects. It captures 8000 range points per second with a 5.5 Hz rotation scan rate, enabling reliable obstacle detection and environmental modeling. With a detection range of up to 12 meters, it's a core sensor for autonomous vehicles and interactive installations.

Compatibility
The RPLidar A1 works with popular microcontrollers like Arduino and STM32, as well as single-board computers such as Raspberry Pi (via USB or UART). Ensure 3.3V logic levels for direct UART connections; use a level shifter if interfacing with 5V boards. It pairs well with motor drivers and ROS for advanced robotics applications.
Wiring Notes
Connect VCC to a 5V supply and GND to ground. For serial communication, connect TX to RX and RX to TX on your controller (3.3V levels). The motor is driven internally; no external driver needed. A USB adapter is included for easy connection to a PC or Raspberry Pi.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi?
Yes, the RPLidar A1 works seamlessly with Raspberry Pi. Connect via USB and use the Rosa or SLAMTEC's SDK for rapid integration; ROS packages are available for SLAM.
Does it need an external motor driver?
No, the RPLidar A1 has a built-in motor and driver. Just power it with 5V, and the rotation starts automatically when data acquisition is initiated.
What is the difference between A1 and A2 models?
The A2 offers a higher sampling rate (16k points/sec) and a longer range (16 m). The A1 remains a solid choice for budget-conscious projects needing moderate performance.
