LDROBOT STP-23L 7.5m Single Point Lidar Sensor + Ethernet Adapter Module + Serial Port Adapter Module

LDROBOT STP-23L 7.5m Single Point Lidar Sensor + Ethernet Adapter Module + Serial Port Adapter Module

Difference between STP-23 and STP-23L:
* The STP-23L module offers better cost-effectiveness, a smaller size, and a lower data output frequency, allowing for transmission at lower baud rates and achieving higher single measurement accuracy. In contrast, the STP-23 features a built-in high-frequency laser ranging module at the LiDAR level, offering an ultra-high sampling frequency and the ability to average multiple data points, resulting in enhanced data stability. Additionally, the STP-23 has a larger ranging capability.

Advantages of STP-23L:
* TTL to USB adapter module can be directly connected to a computer or used with a microcontroller for data collection.
* Ethernet transmission offers faster and more stable data transmission
* Distance Measurement Range: 0.07m ~ 7.5m
* Measurement Frequency: 120Hz
* Measurement Accuracy: Within 0.5cm
* Ambient Light Immunity: 60KLux

Features of STP-23L:
* STP-23L High-Precision Laser Distance Measurement Module: It supports ROS1/ROS2 and provides STM32 data collection code.
* The laser ranging module based on the TOF principle has higher stability and better light resistance.
* The maximum measurement distance of STP-23L is up to 7.5m.
* STP-23L has a sampling frequency of 120Hz.
* Millimeter-level measurement accuracy
* It supports indoor and outdoor use, effectively avoiding strong light interference, making ranging performance more stable. And it enables high-frequency and high-precision indoor and outdoor distance measurement.
* Fully compatible with ROS1 and ROS2 systems, it provides SDKs for these two systems, and provides relevant technical support.
* ROS1/ROS2 Calculation SDK Provided: We offer a four-port serial distance measurement ROS1 & ROS2 calculation SDK, showcasing its advantages. It seamlessly integrates with both ROS1 and ROS2 systems, making it easy to adapt to mature projects based on ROS1 or new developments transitioning to ROS2. For data processing, we parse the underlying data and publish it as ROS topics, allowing developers to quickly access and utilize the data. This significantly improves development efficiency and simplifies data interaction.
* With its compact structural design, it offers lower power consumption, higher cost-effectiveness, and easier installation.
* It uses a low-power infrared laser emitter as the light source, driven by modulated pulses. The laser emits for only a very short duration, complying with FDA Class 1 eye safety standards.
* Supports Windows environment and provides Windows client software
* Supports serial port reading of raw data: We provide example source code for distance data acquisition using both the STM32 standard library and HAL library.
* Provides practical application examples: An STM32-based robot equipped with the STP-23L distance measurement module can follow a straight line along a wall (at least two STP-23L modules are required to implement this functionality).
* Full Python Serial Port Support for Windows and Ubuntu: To make it easier for users to get started with the distance measurement module, the STP-23L provides Python 2.7 and Python 3.0 code, compatible with both Windows and Ubuntu environments. The raw data from the measurement module is parsed and then output, allowing users to easily view the distance data of objects detected by the module.
* ROS support for Linux environment
* Application Scenarios: ROS-based robots, maker and educational projects, robotic vacuum cleaners, autonomous driving, and drone obstacle avoidance

Documentation Information:
* We can provide English resources, including source code with English comments, English documentation, and video tutorials with English subtitles. Please contact customer service after purchasing the product if needed.

Optional Ethernet Adapter Module:
* Data transmission via Ethernet offers faster speeds compared to serial communication. It supports long-distance signal transmission, and frees up USB port resources. Data can be collected directly through the Ethernet ports of main controllers such as Orin Nano and Raspberry Pi.
