NRF24L01

It is a single-chip transceiver chip that operates in the 2.4-2.5GHz world-wide ISM band. The wireless transceiver includes: frequency generator enhanced SchockBurstTM mode controller power amplifier crystal amplifier modulator demodulator output power channel selection and protocol settings Very low current consumption can be set through the SPI interface. When the transmit power is 6dBm in the transmit mode, the current consumption is 9.0mA. The receive mode is 12.3mA in the power-down mode and the standby mode has a lower current consumption mode.

Supports six channels of data reception

1.Low operating voltage:1.9~3.6VLow voltage operation

2.High rate:2MbpsDue to the short transmission time in the air, the collision phenomenon in wireless transmission is greatly reduced (software sets the air transmission rate of 1Mbps or 2Mbps)

3.Multi-frequency point:125Frequency, meeting the needs of multi-point communication and frequency hopping communication

4.Ultra small: built in2.4GHzAntenna, small size, 15x29mm (including antenna)

5.Low power consumption: When operating in the answer mode communication, fast air transmission and startup time greatly reduce current consumption.

6.Low application cost: NRF24L01 Integrated with allRFProtocol-related high-speed signal processing parts, such as: automatic retransmission of lost data packets and automatic generation of response signals, etc., NRF24L01SPIThe interface can utilize the hardware of the microcontrollerSPIPort connection or use single chipI/OMouth simulation, internalFIFOIt can interface with a variety of high and low speed microprocessors, making it easy to use low-cost microcontrollers.

7.Easy to develop: Since 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 number of retransmissions can be controlled by software Automatically store the packet auto-answer function that does not receive the response signal. After receiving the valid data, the module automatically sends the response signal without additional programming carrier detection—fixed frequency detection. Built-in hardwareCRCError detection and point-to-multipoint communication address control packet transmission error counter and carrier detection function can be used for frequency hopping setting. Six channel receiving channel addresses can be set at the same time. It can selectively open the receiving channel standard pin Dip2.54MM spacing interface. Embedded applications
