- ISM band receiver module implemented with unique PLL and zero IF design approach
- Works with FSK modulated signal ranging from 433, 868 and 915MHz bands
- Comply with FCC and ETSI regulation
- SPI interface is used to communicate with micro-controller for parameter setting
- Works with RFM02 transmitter module at 433MHz band
- Pair of module can work up to 300m in free open air
- Packages: DIP, SMD1 and SMD2 (SMD2 is thinner and smaller than SMD1 due to the crystal size)
