RLINK Handbook


RLINK is a long-distance wireless data link communication module developed by blicube.LLC, supporting Point to Point and Point to Multipoint. Using two RLINK modules to form a pair of data links for mutual communication, when one connected to the device end and the other connected to the computer end. With three or more RLINK modules, it can be used for Point to Multipoint.

Based on bulit-in P900 module, RLINK has the characteristics of high transmission power, high link rate, high receiving sensitivity, etc. The ground-to-air communication distance is up to 30+KM, the transmitting power can reach 1W , besides the module supports wide voltage input (5~55V) and high-speed frequency hopping. The module has the operating temperature range of -40 to 80 degrees, with shell of CNC aviation aluminum alloy materials.
