NRF24L01P + PA + LNA Division I for the ultra-long-distance data transmission specially developed high-powerand high sensitivity wireless module 2.4G ISM band NRF24L01P + PA + LNA wireless module to work in thelicense-free, can be point-to-pointapplications, can also be composed of a star network, NRF24L01P + PA + LNA wireless module core Norway NORDIC company's latest high-performance wireless Digital transmission chip NRF24L01 +, with the Division of Professional Design professional full two-way RF power amplifier high power PA and LNA chip, RF switches, bandpass filters, etc., makes effective communicationdistance greatly expand. RF part, the Secretary has done a lot of optimization matching debugging, the emission efficiency to achieve the highest harmonic minimum Makes NRF24L01P + PA + LNA wireless module of RF interference to the external equipment reaches a minimum, while not susceptible to interference from other devices, greatly Uploader High stability of the work. NRF24L01P + PA + LNA wireless module integration is extremely high, the size of only 41mm x 15.5mm,convenient embedded In any tight space products, customers can increase an MCU through the SPI port to control NRF24L01P + PA +LNA Wireless module to complete the design of ultra-long-range wireless data transmission system completely eliminates the need for the RF part of the R & D Worry about slash R & D spending and shorten the development cycle Colour:black Material:plastic Size:1000 meters long distance Package Contents: 4 x Wireless Transceiver Module 4 x SMA Antenna Only the above package content, other products are not included.
