How to compare fairly
Compare range on the same target reflectivity, check that the interface and logic level match your host, and compare the published single-unit price including shipping. ERDI prices and quantity bands are public on each model page; drivers for ArduPilot, ROS 2, Arduino and Raspberry Pi are open in erdi-lrf-drivers. The open module database holds both vendors' figures with sources.
FAQ
Which ERDI module is closest to the Lumispot LSP-LRF series?
By published range class and interface, the closest ERDI models are LRF0105C, LRF0310C, LRF0405C. Check the range condition on each before deciding; the vendors quote different targets.
Which is the lowest-priced ERDI alternative to the Lumispot LSP-LRF series?
Among the models listed, the LRF0105C has the lowest published price, From $300 per unit with shipping included.
Which is the lightest ERDI alternative to the Lumispot LSP-LRF series?
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.
