LRF50VB · 905 nm Single-Point LiDAR Sensor
LRF50VB UART wiring, pinout and serial protocol
The LRF50VB talks UART/IIC and is powered from 3.3–5 V DC. Wire TX to the host RX, RX to the host TX, share ground, then send one of the commands below.

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.
