SMAKN Mini NRF24L01 2-4GHz SMD Wireless Transceiver Module for Arduino

*High rate: 2 Mbps, due to the air transport time is very short, greatly reduce the collision phenomenon in the wireless transmission (software setting 1 Mbps or air transmission rate of 2 Mbps). *Multi-frequency points: 125 frequency points, meet the requirements of multipoint communication and frequency hopping communication. *Subminiature: built-in 2.4 GHz antenna, small size, 15 x29mm (including the antenna). *Low power consumption: when work in answer mode communication, fast air transport and the startup time, greatly reduce the current consumption. *Low cost of application: NRF24L01 integrates all the high-speed signal processing part of RF protocol related, such as: automatic retransmission packets lost and automatically generate response signal, NRF24L01 SPI interface can take advantage of the single chip microcomputer hardware SPI port connection or use the microcontroller I/O port to simulate, internal FIFO can with all kinds of high speed microprocessor interface, easy to use low cost single chip microcomputer. *To facilitate development: due to the link layer is fully integrated in the module, very easy to develop. Automatic retransmission function, automatically detect and resend the lost packets and retransmission software control automatic storage time and retransmission times can not yet received response signal packet automatic reply function, after receipt of a valid data, the module to send response signal automatically, without prior programming carrier detect - fixed frequency detection Built-in hardware CRC error detection and point to multipoint communication address control packet transmission error detection function can be used to counter and carrier frequency hopping Settings can be set up at the same time all receiver address, can be selectively receiving opening standard pin Dip2.54 MM spacing interface, convenient for embedded application.
