| LRF50VB | 0.05–50 m (90% reflectivity); 0.05–20 m (10% reflectivity) | 905 nm | UART/IIC | ±5 cm (<5 m); 1% (≥5 m) | 1.3 g | From $20 per unit |
| LRF100H | 0.05–100 m (90% reflectivity); 0.05–30 m (10% reflectivity) | 905 nm | UART, IIC | ±10 cm (<10 m); 1% (≥10 m) | 20 ± 2 g | From $80 per unit |
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 Garmin LIDAR-Lite v4 LED?
By published range class and interface, the closest ERDI models are LRF10VB, LRF22VB, LRF50H. Check the range condition on each before deciding; the vendors quote different targets.
Which is the lowest-priced ERDI alternative to the Garmin LIDAR-Lite v4 LED?
Among the models listed, the LRF10VB has the lowest published price, From $6 per unit with shipping included.
Which is the lightest ERDI alternative to the Garmin LIDAR-Lite v4 LED?
The LRF10VB at 1 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.
