Product overview
The Radiolink R12DSM from RadioLink Electronic Limited is a miniature radio receiver for integration into aircraft control systems, including racing drones. Its hardware combines detachable antennas with 12-channel SBUS/PPM signal output. A 30*15 mm footprint and 2.5g weight make it suitable for installations with limited space and weight allowance, including mini racing drones. The product is a receiver component; its role is to provide control signals to a flight controller within the aircraft installation.
Integration requires a 4.8~6V supply, with operating current specified as 38-45mA at 5V. Supported transmitters are AT10II, AT10, AT9S Pro, AT9S and AT9. The radio architecture combines DSSS and FHSS spread spectrum, 16-channel pseudo-random frequency hopping and QPSK modulation. The specified airborne control distance is 4000 meters (2.48Miles), qualified by unobstructed, interference-free test conditions and local regulations. Model-voltage display requires pairing with a PRM-01 flight module, making that telemetry function dependent on the additional module.
