Overview
The RadioLink R12DS is a 12-channel high-performance 2.4GHz receiver supporting both PWM and SBUS output. Utilizing DSSS and FHSS hybrid spread spectrum technology, it offers a robust anti-interference signal, ultra-low latency, and up to 4,000 meters of control distance. Compatible with AT9/AT9S/AT9S Pro/AT10/AT10II transmitters, it supports real-time telemetry and is ideal for aircraft, multirotors, fixed-wings, cars, boats, and robotic applications.
