Product overview
The ERDI LASER ERDILRF LRF0305C brings pulsed distance measurement to lightweight drone payloads, compact handheld rangefinders and smart optics. It supports distance measurement for mapping and inspection cameras on small airframes, as well as digital observation devices that overlay distance on a display. Built around a MINI-100 laser source, the module operates at 1535±5nm with laser energy ≥100 μJ, beam divergence ≤0.6 mrad and an approximately 7.4 mrad field of view. Ranging frequency is 1Hz ~10Hz, with ±1 m accuracy and detection of up to three targets.
The module connects through UART(TTL 3.3V) and accepts a DC 3~5V supply. Across the full temperature range at 5 V, operating consumption is ≤0.9 W at 1 Hz and less than 1.5 W at 10 Hz; peak consumption is less than 3 W at 5 V. Start-up takes ≤350 ms, with subsequent response times less than 20 ms. Operating temperature extends from −40 °C to +70 °C. The module measures ≤27 × 25 × 15.5 mm (L×W×H) and is assembled, aligned, calibrated and accepted in-house in Chengdu.
