Micoair 915MHz 30km LoRa Telemetry Module LR900-F for Drones & Robotics

Overview

Meet the Micoair LR900-F, a 915 MHz long-range LoRa telemetry module designed for drones and robotics. With an outdoor line-of-sight reach of 30 km or more and up to 500 mW of transmit power, it aims to deliver dependable links across open spaces, mountains, and urban environments while keeping installation straightforward for engineers and hobbyists alike.

Built to work seamlessly with popular flight stacks such as Pixhawk, ArduPilot, and PX4, this module emphasizes reliability and flexibility without locking you into a single workflow. Leveraging LoRa spread spectrum technology helps maintain data clarity in crowded RF spaces, enabling you to plan longer missions with confidence.

Key Advantages

• 500 mW maximum transmission power and 30 km+ outdoor line-of-sight range for long-range links.
• LoRa spread spectrum technology for reliable, interference-resistant communication.
• Dual Port Flexibility: TTL serial and Type-C USB ports support direct device connections and PC/Android use.
• Simple setup with two matching address parameters in duplex mode for quick interconnection.
• On-board SAW filtering, FHSS self-avoidance frequency hopping, and diversity antenna support for optimal performance.

Real-world Scenarios

• Long-range telemetry for drones running Pixhawk, ArduPilot, or PX4 stacks in open fields or varied terrain.
• Robotics, autonomous vehicles, or remote sensing setups requiring dependable data links across distance or obstacles.
• Remote inspection, field testing, or search-and-rescue operations where robust RF performance can reduce link retries.

Setup & Integration

The module uses a simple duplex configuration: two matching address parameters to enable direct interconnection. Use the TTL serial port to connect to flight controllers or other devices, and the Type-C USB port for computer or Android phone setup and diagnostics. For best results, orient the diversity antennas to maximize signal diversity and maintain line-of-sight whenever possible. This approach helps you tailor the system to your platform without sacrificing flexibility.
