ISM RFM12B-868S2P 868 MHz radio module

Description

RFM12B-868S2P is an ISM radio module in an SMD enclosure (2.2 mm pitch). It operates on the 868 MHz frequency. The module complies with FCC, ETSI regulations. The SPI interface is used to communicate with the microcontroller. The module is a complete analog RF transceiver with PLL synthesizer with PA, LNA, converter mixers, filters and baseband amplifiers and demodulator. All required RF functions are integrated. RFM12B significantly reduces the microcontroller load due to the integrated digital data processing function. The module will be used in such projects as remote control of devices, toys or wireless data acquisition from sensors.
