General Introduction
RFM02 is a low costing ISM band transmitter
module implemented with unique PLL approach. It
works with FSK modulated signal ranges from
433/868/915MHZ bands, comply with FCC, ETSI
regulation. The SPI interface is used to
communicate with microcontroller for parameter
setting. RFM02 works with RFM01 receiver module.
At 433MHZ band, the pair of module can work up to
300m in the free open air.
