LR1500E2 key specifications

Item	Published value
Model	LR1500E2
Published range	4–1,500 m (Standard range; actual reach depends on target and environment.)
Wavelength	905 ± 5 nm
Interface	UART-TTL
Accuracy	Both sources give ±1 m (6 m ≤ D < 500 m) and ±(0.5 m + 0.001D) for the second interval. The archived factory pack table ends the second interval at 1,000 m; the current official public PDF v1.2 lists 500 m ≤ D ≤ 1,500 m. Sources differ; confirm the applicable supplied revision.
Update rate	2–10 Hz (adaptive)
Supply	3.3–5 V
Weight	≤10 g
Dimensions	Archived factory pack table: 25.65 × 13.2 × 24.6 mm. Current official public PDF v1.2: 25.7 ± 0.1 mm × 13.3 ± 0.1 mm × 24.6 mm (+0/−0.05 mm). Sources differ; confirm the supplied drawing.
Laser safety	Class 1
Price	From $40 per unit

Parameter	Published value	Condition / note
Laser wavelength	905 ± 5 nm
Measurement range	4–1,500 m	Standard range; actual reach depends on target and environment.
Ranging accuracy	Both sources give ±1 m (6 m ≤ D < 500 m) and ±(0.5 m + 0.001D) for the second interval. The archived factory pack table ends the second interval at 1,000 m; the current official public PDF v1.2 lists 500 m ≤ D ≤ 1,500 m. Sources differ; confirm the applicable supplied revision.	Whiteboard target, 90% reflectivity: 2.3 × 2.3 m for the first distance interval; 2.3 × 4.6 m for the second.
Measurement update rate	2–10 Hz (adaptive)	Completed distance outputs; not the optical pulse-repetition rate.
Interface	UART-TTL	Custom configurations are specified separately.
Baud rate	115200 bps
Supply voltage	3.3–5 V
Operating temperature	−20 °C to +55 °C
Storage temperature	−40 °C to +60 °C
Mechanical drawing dimensions	Archived factory pack table: 25.65 × 13.2 × 24.6 mm. Current official public PDF v1.2: 25.7 ± 0.1 mm × 13.3 ± 0.1 mm × 24.6 mm (+0/−0.05 mm). Sources differ; confirm the supplied drawing.	Archived factory pack: table p2 gives 13.2 mm, while the drawing p4 labels 13.05 mm. The current official public PDF v1.2 p3 gives a different nominal envelope with tolerances. Source documents differ; confirm the applicable supplied drawing and connector envelope before design-in. Archive/publication dates do not identify the delivered revision.
Weight	≤10 g
Ingress protection	IP67	Lens cavity only; not a blanket rating for the exposed board or the complete host product.
