4pcs NRF24L01+ 2.4GHz Antenna Wireless Transceiver RF Module 1.9~3.6V

Description:
NRF24L01 is a single chip radio transceiver for the worldwide 2.4-2.5 GHz ISM band.The transceiver consists of a frequency synthesizer, a mode controller, a power amplifier, a crystal  amplifier, a demodulator. Output power channel selection and protocol can be set by Serial Peripheral Interface to set ultra-low current consumption. When working under sending mode,sending power is 6dBM and current consumption is 9.0mA. Receiving mode is 12.3mA, lower at power off and standby mode.

Features:
Low working voltage: 1.9 ~ 3.6V low-voltage work.
High speed: 2Mbps. Due to the short time of air transmission, the collision phenomenon in wireless transmission is greatly reduced (software setting 1Mbps or 2Mbps air transmission rate)
Multi-frequency point: 125 frequency point, which meets the need of multi-point communication and frequency hopping communication. Super small: built-in 2.4GHz antenna, compact size
Low power consumption: when working in response mode communication, fast air transmission and start-up time greatly reduce current consumption.
Low cost of application: NRF24L01 integrates all the high-speed signal processing part related to RF protocol, such as: automatic retransmission lost packets and automatically generate response signal, NRF24L01 Serial Peripheral Interface can use single chip microcomputer hardware Serial Peripheral Interface port connection or use the micro-controller I/O port to simulate, internal FIFO can connect with all kinds of high speed microprocessor interface, easy to use low cost single chip microcomputer.
Easy to develop: because the link layer is fully integrated on the module, it is very easy to develop. Automatic retransmission function, automatically detect and resend lost packets and automatic retransmission time and number of times can be controlled by software. Automatically store signal packets that not receive response signal, automatic response function, after receipt of a valid data, the module sends response signal automatically, without other programming carrier detect - fixed frequency detection built-in hardware CRC error detection  point to multi-point communication address control packet transmission error counter and carrier wave detection function can be used for frequency hopping settings.Six channel receiver address can be set up at the same time, can be selectively receiving opening standard pin Dip 2.54 MM spacing interface, convenient for embedded application.
