RFM12B-S2 Wireless Transceiver "(arduino compatible)" - Bangalore

" The RFM12B is a great inexpensive option for wireless communication; it's an ISM band FSK transceiver module implemented with a unique PLL. These modules operate in the 434MHZ band and fully comply with FCC and ETSI regulations.

This module has a wide voltage supply range of 2.2-3.8VDC. An SPI interface is used to send data and configure the RFM12 module. The configuration commands, described in the RF12 IC Datasheet linked below, can be used to set the data rate, frequency band, wake-up timer, transfer data, receive data from the 16-bit FIFO, and much more.

The module comes in a 14-pin SMD package, with pins spaced by 2mm. Check below for a breakout board.
