Product overview
The ERDI Laser LRF3000A1 laser rangefinder module provides distance measurements for UAV rangefinding and laser altimeter integration with Pixhawk / ArduPilot. Its 905 ± 10 nm laser carries a Class 1 classification under IEC 60825-1. Maximum range is ≥3,000 m with a 70%-reflectivity building target in clear weather and visibility ≥4 km. Grass or dark soil produces a shorter range. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu.
The module operates from 3.3–5 V DC and communicates through UART at 3.3 V TTL, with 115200 bps as the default and 9600 bps also supported. At 115200 baud, it streams 8 B / 2 B frames with distance output in metres over 1.0-3000.0 m. Pixhawk TELEM wiring connects module TX to TELEM RX, module RX to TELEM TX and ground to ground. ArduPilot integration resources provide a Lua fallback script while the submitted ERDI serial driver awaits release.
