You can select your preferred range at the time of purchase to match your specific drone operation requirements.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply does this TTL fibre optic module require?\u003c\/h4\u003e\n\u003cp\u003eA: The module operates on DC 5.5V to 26V, which is compatible with standard 2S to 6S LiPo drone batteries. Ensure the supply stays within this range — below 5V may cause chip malfunction, and above 26V risks permanent damage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this module compatible with CRSF-based flight controllers and remote control systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The module features an MX-SH1.0mm-5P interface that supports the CRSF protocol, making it compatible with popular CRSF-based flight controllers and remote control receivers. It also supports CVBS video for analogue FPV systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the airborne and ground units?\u003c\/h4\u003e\n\u003cp\u003eA: The airborne unit transmits at 1310 nm fibre optic wavelength and connects to the drone's flight controller. The ground unit operates at 1550 nm and connects to your remote control receiver and video display or VTX. The dual-wavelength design ensures clear, full-duplex signal separation for reliable two-way communication.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
