General Introduction
RFM01
RFM01 is a low costing ISM band receiver module
implemented with unique PLL and zero IF design approach.
It works with FSK modulated signal ranges from
315/433/868/915MHZ bands, comply with FCC, ETSI
regulation. The SPI interface is used to communicate with
microcontroller for parameter setting. RFM01 works with
RFM02 transmitter module. At 433MHZ band, the pair of
module can work up to 300m in the free open air.
