FSK RF COB Module(Receiver)

RFM01 is a low costing ISM band receiver module implemented with unique PLL and zero IF design approach. It works with FSK or ASK 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 RFM02A/B transmitter module. At 433MHZ band, the pair of module can work up to 300m in the free open air.
