RFM02-868-S1 Quasar

RFM02 Datasheet REV1.2 ISM BAND FSK TRANSMITTER MODULE RFM02 the purpose of this spec covers mainly for the RFM02 physical characteristic of the module, for register configure and its related command info please refer to RF02 data sheets General Introduction RFM02 is a low costing ISM band transmitter module implemented with unique PLL approach. It works with FSK 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. RFM02 works with RFM01 receiver module. At 433MHZ band, the pair of module can work up to 300m in the free open air. Features: Low costing, high performance and price ratio Tuning free during production FSK transmission PLL employed Fast PLL lock time High resolution PLL with 2.5 KHz step Programmable frequency deviation (from 30 kHz to 210 kHz, step 30 kHz) Programmable output power High data rate (up to 115.2 kbps with FSK modulation) Differential antenna output Automatic antenna tuning SPI interface Clock and reset signal output for external MCU use 10MHz crystal for PLL reference Programmable crystal load capacitor bank Wakeup timer low battery detection 2.2V - 5.4V power supply Low power consumption stand by current less than 0.3A Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales hoperf.com RFM02 Datasheet REV1.2 Typical Application Remote control Remote sensor Wireless data collection Home security system Toys Tire pressure monitoring system Pin Definition SMD DIP Definition TYPE function FSK DI FSK data input CLK DO clock out for MCU (1 MHz-10 MHz) VDD S Positive power supply nIRQ DO Interrupts request outputactive low SDI DI SPI data input SCK DI SPI clock input VSS S negative power supply, GND nSEL DI Chip select (active low) Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales hoperf.com
