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.Features:1) Low costing, high performance and price ratio2) Tuning free during production3) FSK or ASK reception4) PLL employed5) Fast PLL lock time6) High resolution PLL with 2.5kHz step7) Programmable frequency deviation (from 30kHz to 240kHz, step 30kHz)8) Programmable output power9) High data rate: up to 115.2 Kbps with FSK modulation, with ASK modulation10) Highest data rate is 256Kbps11) Differential antenna outputs12) Automatic antenna tuning13) SPI interface14) Clock and reset signal output for external MCU use15) 10MHz crystal for PLL reference16) Programmable crystal load capacitor bank17) Wakeup timer18) Low battery detection19) 2.2V - 5.4V power supply20) Low power consumption21) Stand by current less than 0.3
