FSK RF COB Module(Transmitter)

1.RFM02A is a low costing ISM band transmitter module implemented with unique PLL approach. It works with FSK or ASK modulated signal ranges from 315/433/868/915MHZ bands(if 315MHz is no wanted,please select RFM02B), comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. RFM02A works with RFM01 receiver module. At 433MHZ band, the pair of module can work up to 300m in the free open air.



2.RFM02B is a low costing ISM band transmitter module implemented with unique PLL approach. It works with FSK or ASK 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. RFM02B works with RFM01 receiver module. At 433MHZ band, the pair of module can work up to 300m in the free open air.
