Low cost ISM Band receiver module implemented with unique PLL and zero IF design approach , and work with FSK modulation signal ranges from 315/433/868/915MHz band, comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. RXM01 work with TXM02 transceiver module at 433MHz band. The pair of module can work up to 300 meter in open air (line of sight )
