LR1000E4 · 905 nm Laser Rangefinder Module
LR1000E4 on Pixhawk / ArduPilot: rangefinder setup
The LR1000E4 streams 8 B / 2 B frames at 115200 baud in m over 4.0-1000.0 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. Interface: UART-TTL.

FAQ
What is the maximum range of the LR1000E4?
The published range is 4–1,000 m (Standard range; actual reach depends on target and environment.). 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 LR1000E4 use?
The published communication interface is UART-TTL @ 115200 bps.
What laser wavelength does the LR1000E4 use?
The published wavelength is 905 ± 5 nm; laser safety entry: Class 1.
How much does the LR1000E4 cost?
The published single-unit price of the LR1000E4 is $80, falling to $30 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
Does ArduPilot support the LR1000E4 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.
