LRF50VB · 905 nm Single-Point LiDAR Sensor
LRF50VB on Pixhawk / ArduPilot: rangefinder setup
The LRF50VB streams 4 B / 2 B frames at 460800 baud in mm over 0.05-50.0 m. ArduPilot support is in the public driver work linked below; the flight-controller side is a serial port and a handful of RNGFND parameters.
Wiring to a Pixhawk TELEM port
Module TX → TELEM RX, module RX → TELEM TX, GND → GND. Power: 3.3–5 V DC. Interface: UART/IIC.

FAQ
What is the maximum range of the LRF50VB?
The published range is 0.05–50 m (90% reflectivity); 0.05–20 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity.). A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.
Which interface does the LRF50VB use?
The published communication interface is UART/IIC.
What laser wavelength does the LRF50VB use?
The published wavelength is 905 nm; laser safety entry: Class 1.
How much does the LRF50VB cost?
The published single-unit price of the LRF50VB is $70, falling to $20 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
Does ArduPilot support the LRF50VB natively?
A serial driver for the ERDI frame format was submitted to ArduPilot (pull request 34983). Until it ships in a release, the repository above provides a Lua script that parses the same frames and feeds the rangefinder backend.
