LR1200E2 is a 905 nm laser ranging module with a source-table measuring range of 4-1200 m, IEC Class 1 eye-safe. Ranging accuracy is +/-1 m from 6-500 m and +/-(50 cm + 0.1% x d) from 500-1000 m, at 2-10 Hz adaptive frequency. It uses a UART-TTL interface at 115200 bps, runs on 3.3-5 V DC drawing about 0.4-1 W, and starts up in under 200 ms. The module measures 25.65 x 13.2 x 24.6 mm, weighs under 10 g.
