NRF24L01+ 2.4GHz antenna module wireless transceiver

The NRF24L01 is a monolithic transceiver chip operating in the world's common ISM band of 2.4-2.5GHz. Wireless transceivers include: SchockBurstTM enhanced frequency generator mode power controller crystal amplifier amplifier Modulator Demodulator The output of the power channel selection and setting protocol can be set to very low current consumption via the SPI interface. When the transmission power is 6dBm in transmission mode, the current consumption is 9.0mA. Receive mode is 12.3mA and lower current consumption mode in standby mode. ISM band open ball, maximum 0dBm transmitting power, free license to use. Supports six data reception channels1. Low operating voltage: low operating voltage 1.9 ~ 3.6V2. High rate: 2Mbps, because the air transmission time is very short, greatly reduces the collision in wireless transmission (software sets the air transfer rate 1Mbps or 2Mbps) 3. Multi-frequency: 125 frequency points to meet the needs of multi-point communication and frequency jump communication4. Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm (including antenna) 5. Low power consumption: when working in response mode communication, fast air transmission and start time, greatly reducing current consumption.6. Low application cost: NRF24L01 integrates all high -speed signal processing related to RF protocol, such as: automatic retransmission of lost data packets and automatically generate response signals, NRF24L01 SPI interface can use SPI microcontroller interface to connect or use ports I / O microcontroller to simulate, internal FIFO can be with a variety of high and low speed microprocessor interface, easy to use low -cost single chip.7. Easy to develop: because the link layer is fully integrated on the module, it is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost data packets, retransmission time and the number of retransmission software control can automatically receive a response signal does not receive a packet automatic response function, after receiving valid data, the module automatically sends a signal response, No additional programming carrier detection-fixed frequency detection hardware built-in CRC error detection and address communication point-to-multipoint packet control transmission error counter and carrier detection function can be used for frequency jump settings can be set to six simultaneously receive channel addresses, can be selectively open accept standard channel pin Dip2.54MM field interface for easy embedded application.
