Integration
All UART models share one frame family documented in erdi-lrf-drivers, with ArduPilot, ROS 2, Arduino, Raspberry Pi and STM32 examples. Each model page links its own wiring, driver and price pages.
FAQ
Which is the lowest-priced 3 km laser rangefinder module?
Among the models listed, the LRF3000A1 has the lowest published price, From $80 per unit with shipping included.
Which is the lightest 3 km laser rangefinder module?
The LRF3000A1 at 12 ± 0.5 g is the lightest of the models listed.
Why does every range figure show a condition?
Vendors measure range on different targets (white board, building, 10 percent reflectivity) and in different visibility. A number without its condition cannot be compared, so this page lists the condition next to each range.
