Overview:

RFM70 is a GFSK transceiver module operating in the world wide ISM frequency band at 2400 - 2483.5 MHz. Burst mode transmission and up to 2Mbps air data rate make them suitable for applications requiring ultra low power consumption.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.
