Application and integration notes

The module requires DC 5–28 V input. Its listed mass is ≤40 g, and its envelope is ≤50 × 23 × 33.5 mm. Review these values against the host platform's power supply, mounting space and communications interface. For an integration inquiry, provide the target type, expected distance, atmospheric conditions and required update rate. Confirm the communications protocol, connector pinout and acceptance test before completing the system design.

Host-system acceptance

For the TTL connection, confirm the logic-voltage specification as well as the connector pinout and message format. The supply-voltage value does not define the TTL signal level. Include nearby targets in the acceptance test so the stated minimum-range specification is assessed alongside long-range performance.
