Overview
The RadioLink R8SM is an ultra-compact 8-channel mini receiver designed specifically for racing drones and multicopters. Weighing only 2g and measuring just 18×13mm (0.70"×0.51"), the R8SM features an impressive control distance of up to 2000 meters (1.24 miles) in the air. It supports both SBUS and PPM signal output and operates on the 2.4GHz ISM band using FHSS with 67-channel pseudo-random frequency hopping for robust anti-interference performance. With a wide 3-6V operating voltage range and a precision of 4096 (0.25μs per section), it is compatible with various flight controllers including PIXHAWK, MINI PIX, APM, F4, and F7.
