2.45ghz Radio Frequency (Rf) Module

The 2.45GHz Radio Frequency (RF) Module adds a range of enhanced features, including increased operating voltage range, reduced supply current in all operating modes, higher data rate options.The Module provides a complete Controller SPI to antenna wireless MODEMs. The Module is designed to implement wireless device links operating in the worldwide 2.4 GHz ISM frequency band. The Module has an SPI interface supporting communication between an application MCU and Module. The SPI interface supports single-byte and multi-byte serial transfers using either 4-pin or 3-pin interfacing. The SPI communications interface consists of Slave Select (SS), Serial Clock (SCK), Master Out-Slave In (MOSI), Master In-Slave Out (MISO), or Serial Data (SDAT).
Where can it be used:
1) Wireless Keyboards and Mice.
2) Wireless Game pads.
3) Remote Controls.
4) Toys.
5) VOIP and Wireless Headsets.
6) Consumer Electronics.
7) Home Automation.
