We have taken the popular RFM12B and made it easier to use by placing it on a breakout board with standard 0.100" pin spacing.

HopeRF's RFM12B is a single chip, low power, multi-channel FSK transceiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 433 MHz band. The RFM12B transceiver produces a flexible, low cost, and highly integrated solution that does not require production alignments. The chip is a complete analog RF and baseband transceiver. All required RF functions are integrated in module and accessed using the firmware command interface via SPI communication.

Also available in 433MHz.
