Description
FlySky FRM303 2.4GHz 18CH AFHDS 3 Long Range Transmitter RF Module PPM/S.BUS Output for Flysky PL18 EL18 NB4/NB4 Pro Radio Controller
The FlySky FRM303 is a high-performance 2.4GHz 18-channel RF module designed for long-range communication, compatible with Flysky PL18, EL18, and NB4/NB4 Pro radio controllers. It operates on the AFHDS 3 protocol, ensuring reliable frequency hopping. This module features an external replaceable SMA antenna for enhanced signal transmission and supports PPM, S.BUS, and UART inputs. It offers three power supply options and includes a voltage alarm function for external power sources. Ideal for fixed-wing aircraft, racing drones, and relays, it delivers a maximum power of less than 20dBm, with a range exceeding 3500 meters under optimal conditions.
