NRF24L01+ 2.4G Wireless Data Transmission Module 8PIN Wireless Board NRF24L01Upgrade Version 1.9-3.6V Low Power Consumption

NRF24L01 is a single-chip transceiver chip that works in the 2.4-2.5GHz world general 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 setting can be set through the SPI interface. Very low current consumption. When working in the transmitting mode, the current consumption is 9.0mA when the transmitting power is 6dBm. The receiving mode is 12.3mA in the power-down mode and the current consumption mode is lower in the standby mode.

The ball opens the ISM frequency band, the maximum transmission power is 0dBm, and it can be used without a license. Support six channels of data reception

1. Low working voltage: 1.9~3.6V low voltage working

2. High rate: 2Mbps, because the air transmission time is very short, which greatly reduces the collision phenomenon in wireless transmission (the 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 start-up time greatly reduce current consumption.

6. Low application cost: NRF24LO1 integrates all the high-speed signal processing parts related to the RF protocol, such as: automatic retransmission of lost data packets and automatic response signals, etc. The SPI interface of NRF24LO1 can be connected with the hardware SPI port of the single-chip microcomputer or use the single-chip microcomputer The I/O port is used for simulation, and there is a FIFO inside that can interface with various high- and low-speed microprocessors, which facilitates the use of low-cost single-chip microcomputers.

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 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 separately Carrier detection-fixed frequency detection Built-in hardware CRC error detection and point-to-multipoint communication address control Packet transmission error counter and carrier detection function can be used for frequency hopping settings. Six receiving channel addresses can be set at the same time, with selectivity Open the receiving channel standard pin Dip2.54MM pitch interface, which is convenient for embedded applications.
