STA-LRM30X is a high-performance long-range laser ranging module. It adopts a 905 nm semiconductor laser device and operates based on the pulsed TOF (Time of Flight) principle, achieving long-distance measurement from 5 m to 3500 m. Featuring ultra-low power consumption, compact design, stable performance and high reliability, it is specially designed for space- and power-constrained scenarios such as handheld mobile devices and miniaturized UAV pods. It can be perfectly integrated with thermal imaging, night vision, visible light and other systems.

| Pin No. | Function description | |||
| 1 | RS232-Tx | |||
| 2 | RS232-Rx | |||
| 3 | Power supply：DC（3.0V – 5.0V） | |||
| 4 | TxEN: When serial port starts to send data frame, TxEN signal is high; After one frame data transmission is over,TxEN signal is low. TxEN Signal can be used to switch from emission to reception as half duplex, such as RS485. |
