RFM01 is a low costing ISM band FSK receiver module implemented with unique PLL and zero IF design approach. It works with FSK modulated signal ranges £Ærom 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.
