Black NRF24L01 Wireless Data Transmission Module

Product Description:

NRF24L01 is a single-chip transceiver chip that works in the 2.4-2.5GHz world-wide ISM frequency band. The wireless transceiver includes: frequency generator enhanced SchockBurstTM mode controller, power amplifier, crystal amplifier, modulator, demodulator, output power, channel selection and protocol The settings can be set through the SPI interface. Very low current consumption, when working in transmit mode, when the transmit power is 6dBm, the current consumption is 9.0mA, and the receive mode is 12.3mA in power-down mode and standby mode. The current consumption mode is lower.

The ball is open to the ISM frequency band, which is a large 0dBm transmit power and is used license-free.

Supports Data Reception Of Six Channels:

1. Low operating voltage: 1.9~3.6V low voltage operation

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

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

4. 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 startup time greatly reduce current consumption.

6. Low application cost: NRF24L01 integrates all high-speed signal processing parts related to the RF protocol, such as: automatic retransmission of lost data packets and automatic generation of response signals, etc. The SPI interface of NRF24L01 can use the hardware SPI port of the microcontroller to connect or use a microcontroller. The I/O port is simulated, and the internal FIFO can interface with various high and low speed microprocessors, which is convenient for using low-cost single-chip microcomputers.

7. Ease of development: 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 retransmission times can be controlled by software to automatically store data packets that have not received a response signal. Automatic response function, after receiving valid data, the module automatically sends a response Signal, no need to program carrier detection - fixed frequency detection built-in hardware CRC error detection and point-to-multipoint communication address control Data packet transmission error counter and carrier detection function can be used for frequency hopping settings Can set six receiving channel addresses at the same time, optional The standard pin of the open receiving channel is Dip2.54MM pitch interface, which is convenient for embedded applications.
