Frequently Asked Questions
What is the range of this 12 km laser rangefinder module?
The reference page lists different ranges by target type: ≥10,000 m for a large target, ≥4,500 m for a vehicle, ≥3,000 m for a human target and ≥1,600 m for a UAV. It also states a maximum range of ≥16,000 m in the overview, without specifying the target conditions.
Which communication interface does the module use?
The reference information is inconsistent: the overview mentions UART (TTL 3.3 V), while the technical table lists RS-422. Confirm the interface for the required configuration before ordering.
What information should I provide for an OEM quotation?
Share your target type, required range, interface, power input, platform envelope, operating conditions and estimated quantity so the Thermstars team can review product fit and provide a quotation.
