1200m Semiconductor Pulse Rangefinder Module

The ERDI LRF1200A is a high-performance semiconductor laser rangefinder module designed for a wide range of applications, including handheld rangefinders, micro UAVs, and rangefinder scopes. It utilizes a 905nm laser diode to achieve a ranging distance of 5 to 1200 meters with exceptional accuracy. It features a UART (TTL_3.3V) data transmission interface and provides upper computer software and a communication protocol command set, making it convenient for users to develop secondary applications.
