ccRF click (MIKROELEKTRONIKA)

ccRF click™ is a low-power 2.4 GHz transceiver designed for the 2400- 2483.5 MHz ISM and SRD frequency bands. It features CC2500 Low-Power 2.4 GHz RF transceiver as well as PCB trace antenna. The CC2500 is integrated with a highly configurable baseband modem that supports various modulation formats and has data rate up to 500 kBaud. Maximum device range is up to 20 meters in open space. ccRF click™ communicates with the target microcontroller via mikroBUS™ SPI, RST and PWM lines. The board is designed to use 3.3V power supply only. All these features make this board ideal for consumer electronics, wireless audio, wireless keyboard and mouse RF remote controls...
