Smart Electronics NRF24L01+Wireless Module Power Enhanced 2.4G Upgraded Wireless Communication Module

NRF24L01 is a single-chip transceiver chip that operates in the 2.4-2.5GHz universal ISM frequency band.

The wireless transceiver includes a frequency generator, enhanced SchockBurstTM mode controller,

power amplifier, crystal amplifier, modulator, demodulator, output power, channel selection,

and protocol settings that can be set through the SPI interface for extremely low current consumption. Open ISM frequency band, maximum transmission power of 0dBm, license free use. Support six channel data reception 1. Low operating voltage: 1.9-3.6V for low voltage operation 2. High speed: 2Mbps. Due to the short air transmission time, it greatly reduces the collision

phenomenon in wireless transmission (software sets the air transmission rate to 1Mbps or 2Mbps) 3. Multi frequency point: 125 frequency points, meeting the needs of multi-point communication and frequency hopping communication 4. Ultra small: Built in 2.4GHz antenna, compact 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 RF protocol, such as automatic retransmission of lost data packets and automatic generation of response signals. The SPI interface of NRF24L01 can be connected to the hardware SPI port of the microcontroller or simulated using the microcontroller I/O port. It has an internal FIFO that can interface with various high-speed and low-speed microprocessors, making it easy to use low-cost microcontrollers. 7. Easy to develop: Due to the complete integration of the link layer on the module, it is very easy to develop. Automatic resend function, automatically detecting and resending lost data packets. The resend time and number can be controlled by software to automatically store data packets that have not received a response signal. After receiving valid data, the module automatically sends a response signal without the need for additional programming. Carrier detection - fixed frequency detection with built-in hardware CRC error detection and point-to-point communication address control. Data packet transmission error counter and carrier detection function can be used for frequency hopping settings. Six receiving channel addresses can be set simultaneously, and the standard Dip2.54MM spacing interface of the receiving channel can be selectively opened for embedded applications
