[Introduction] : As a 100mW full duplex wireless transceiver module, operates at 425-450MHz ,with transparent transmission available, it features FHSS (Frequency-Hopping Spread Spectrum). During transmission, both sides perform frequency-hopping automatically in max 52 channels (the number of FHSS channel and sequence are configurable); It features TDD (Time Division Duplex).
