RFM-75 Module

SKU: OMP-W033 Category:



RFM75 is a GFSK transceiver operating in the world wide ISM frequency band at 2400-2483.5MHz. Burst mode transmission and up to 2Mbps air data rate make them suitable for applications requiring ultra low power consumption.

RFM75 operates in TDD mode, either as a transmitter or as a receiver.

The embedded packet processing engines enable their full operation with a very simple MCU as a radio system. Auto re-transmission and auto acknowledge give reliable link without any MCU interference.
