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 8 km laser rangefinder module?

Among the models listed, the LRF0610C has the lowest published price, From $700 per unit with shipping included.

Which is the lightest 8 km laser rangefinder module?

The LRF0609C at ≤ 62 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.
