Because the link layer is completely integrated in the module, it is very easy to develop. Automatic detection and automatic retransmission of lost packets, retransmission time and times can be controlled by software, and data packets without receiving response signals are automatically stored; after receiving effective data, the module automatically sends response signals without additional programming; 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 The wave detection function can be used for frequency hopping setting, which can set the address of six receiving channels at the same time, and can selectively open the receiving channels. The SPI interface of si24r1 can be connected with the hardware SPI port of SCM or simulated with the I \/ O port of SCM. FIFO can be connected with various high-speed and low-speed microprocessors, which is convenient to use low-cost SCM. \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cimg alt=\"00228-NRF24L01+无线模块-(1)\" src=\"https:\/\/ae01.alicdn.com\/kf\/H53223ad89e7f4b3797ceea9439787fa8Q.jpg\"\u003e\n \u003cimg alt=\"00228-NRF24L01+无线模块-(3)\" src=\"https:\/\/ae01.alicdn.com\/kf\/H554e9a581f8446abbffdec4c871583f0i.jpg\"\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e\n  NRF24L01 + Wireless Module Power-enhanced Type SI24R1 2.4G WIFI Receiving Communication Modular Unit \n\u003c\/div\u003e \n\u003cdiv\u003e\n    \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cdiv\u003e\n   Product parameters: \n \u003c\/div\u003e \n \u003cdiv\u003e\n     \n \u003c\/div\u003e \n \u003cdiv\u003e\n   On board 2.4G PCB antenna, ISM frequency band, standard pin dip 2.54mm spacing interface, small size, convenient for embedded application. \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Support six channel data reception (one to six) \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Support general modulation methods such as GFSK \/ FSK \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Support 2Mbps \/ 1Mbps \/ 250kbps data rate, and can set different transmission power \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Multi frequency point: 126 frequency points, meeting the needs of multi-point communication and frequency hopping communication, 2400mhz ~ 2525mhz, 1MHz frequency hopping step by step \n \u003c\/div\u003e \n \u003cdiv\u003e\n   LDO with internal integration of high PSRR \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Wide power supply voltage range: 1.9 ~ 3.6V, typical 3.3V \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Average emission current as low as 25mA (7dBm) \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Receiving sensitivity: - 96dbm @ 250kbps \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Transmit power up to + 7 ± 1dbm \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Four line SPI interface, up to 10MHz \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Internal integrated intelligent ARQ baseband protocol engine \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Receiving and sending data hardware interrupt output \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Support 1 bit RSSI output \n \u003c\/div\u003e \n \u003cdiv\u003e\n   Working temperature: - 20 ℃ ~ 85 ℃ \n \u003c\/div\u003e \n \u003cdiv\u003e\n   The best transmission distance: less than 240m (250kbp open environment without shielding and electromagnetic interference) reliable distance is recommended to be used within 30% - 50%. \n \u003c\/div\u003e \n \u003cdiv\u003e\n     \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cdiv\u003e\n    Parameter introduction \n  \u003c\/div\u003e \n  \u003cdiv\u003e\n      \n  \u003c\/div\u003e \n  \u003cdiv\u003e\n    1 VCC - power supply, must be between 2.0 and 3.6V \n  \u003c\/div\u003e \n  \u003cdiv\u003e\n    2 GND - ground connection to power reference \n  \u003c\/div\u003e \n  \u003cdiv\u003e\n    3.
