ขาย Nrf 24 L 01 + โมดูลพาวเวอร์ไร้สาย 2 . 4 G Sm ราคาที่ดีที่สุด

Nrf24l01 + Mini module. The market is of the same kind. Small, completely replace the straight plug module. Pi is more favorable Welcome to the sample. Nrf24l01 is a single chip chip working in 2.4-2.5ghz ism, wireless transceivers include: Frequency generator enhanced schockbursttm mode controller power amplifier crystal amplifier modem moder output power channel selection and protocol setting can be set up with spi interface, the current consumption of 9.0 ma when the emission power is 6 dbm is 12.3 ma and current consumption mode is lower in 12.3 ma. Ball open ism band,. 0dbm emission power, no license is allowed. Data reception in support of six-way channels - low working voltage: 1.9~3.6v low voltage work - high rates: 2mbps, due to the short time of air transmission, the collision phenomenon in wireless transmission is greatly reduced (Software setting air transmission rate of 1mbps or 2mbps) - multi-frequency points: 125 frequencies, meeting multi-point communication and frequency hopping communication needs - microsize: Built in 2.4ghz antenna, small size, 15x29mm (Including antennas) - low power consumption: When working in answer mode communication, rapid air transmission and start-up time, the current consumption has been greatly reduced. - low application costs: Nrf 24 l01 integrates all the high-speed signal processing components associated with rf protocols, for example,: Auto-reissued lost packets and automatic response signals, nrf 24 l01 spi interface can be simulated using the hardware spi mouth connection of mcu or mcu i/o, inside fifo can interface with various high and low speed microprocessors, easy to use low-cost single chip machine. - easy to develop: Because the link layer is fully integrated on the module, very easy to develop. Automatic re-launch function, automatic detection and recurrence of lost data packets, the re-release time and the number of re-repetition can control the automatic storage of packet response function that does not receive response signals, upon receipt of valid data, module automatically sends response signal, without the need for separate programming carrier detection-fixed frequency detection of built-in hardware crc error detection and point-to-point communication address control packet transmission error counter and carrier detection function can be used for frequency hopping settings to set up six-way receiver address simultaneously, dip2.54mm, easy to embedding applications.
