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.\u003c\/span\u003e \n  \u003c\/div\u003e \n  \u003cdiv\u003e \n   \u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sbee1e3ccd1d04f2bbe3dd03fcd79f9172.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e \n   \u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S1dc1310080384cf28c085d2bb01722e1m.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e \n  \u003c\/div\u003e \n  \u003cdiv\u003e \n   \u003cspan style=\"font-size:16px\"\u003eNRF24L01 + Wireless Module Power-enhanced Type SI24R1 2.4G WIFI Receiving Communication Modular Unit\u003c\/span\u003e \n  \u003c\/div\u003e \n  \u003cdiv\u003e\n      \n  \u003c\/div\u003e \n  \u003cdiv\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eProduct parameters:\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e\n       \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eOn board 2.4G PCB antenna, ISM frequency band, standard pin dip 2.54mm spacing interface, small size, convenient for embedded application.\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eSupport six channel data reception (one to six)\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eSupport general modulation methods such as GFSK \/ FSK\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eSupport 2Mbps \/ 1Mbps \/ 250kbps data rate, and can set different transmission power\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eMulti frequency point: 126 frequency points, meeting the needs of multi-point communication and frequency hopping communication, 2400mhz ~ 2525mhz, 1MHz frequency hopping step by step\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eLDO with internal integration of high PSRR\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eWide power supply voltage range: 1.9 ~ 3.6V, typical 3.3V\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eAverage emission current as low as 25mA (7dBm)\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eReceiving sensitivity: - 96dbm @ 250kbps\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eTransmit power up to + 7 ± 1dbm\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eFour line SPI interface, up to 10MHz\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eInternal integrated intelligent ARQ baseband protocol engine\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eReceiving and sending data hardware interrupt output\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eSupport 1 bit RSSI output\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eWorking temperature: - 20 ℃ ~ 85 ℃\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cspan style=\"font-size:16px\"\u003eThe best transmission distance: less than 240m (250kbp open environment without shielding and electromagnetic interference) reliable distance is recommended to be used within 30% - 50%.\u003c\/span\u003e \n   \u003c\/div\u003e \n   \u003cdiv\u003e\n       \n   \u003c\/div\u003e \n   \u003cdiv\u003e \n    \u003cdiv\u003e \n     \u003cspan style=\"font-size:16px\"\u003eParameter introduction\u003c\/span\u003e \n    \u003c\/div\u003e \n    \u003cdiv\u003e\n        \n    \u003c\/div\u003e \n    \u003cdiv\u003e \n     \u003cspan style=\"font-size:16px\"\u003e1 VCC - power supply, must be between 2.0 and 3.6V\u003c\/span\u003e \n    \u003c\/div\u003e \n    \u003cdiv\u003e \n     \u003cspan style=\"font-size:16px\"\u003e2 GND - ground connection to power reference\u003c\/span\u003e \n    \u003c\/div\u003e \n    \u003cdiv\u003e \n     \u003cspan style=\"font-size:16px\"\u003e3.
