Mô Đun Sm Không Dây Nrf24L01 2.4 G Chất Lượng Cao

Nrf 24l01 is a single chip that works in 2.4-2.5ghz universal ism frequency band,Wireless transceivers include: frequency generator-enhanced schockbursttm mode controller power amplifier crystal amplifier modulator output power channel selection and protocol setting can be used to set extremely low current consumption through spi interface,The current consumption is 9.0 ma acceptance mode 12.3 ma loss mode and lower current consumption mode under standby mode.

The ball opens the ism band.Large 0 dbm emission power, free of license.
Data reception in support of six channels



- low working voltage: 1.9~3.6v low working voltage



- high speed rate: 2mbps, which greatly reduces collision in wireless transmission due to the short time of air transmission (software sets the rate of air transmission of 1mbps or 2mbps)



- multi-frequency points: 125 frequency points to meet the needs of multi-point and frequency hopping communications



- super compact: built-in 2.4ghz antenna, compact size, 15x29mm (including antenna)



- low power consumption: when working in response mode communication, rapid air transmission and start time greatly reduce current consumption.



- low application cost: nrf 24l01 integrates all high-speed signal processing components associated with rf protocol,For example: automatically redistributing lost packets and automatically generating response signals, etc.,The nrf 24l01 spi interface can be modeled using the hardware spi port connection of the single chip or i/o port of the single chip microcomputer,Inside, fifo can be interfaced with various high and low speed microprocessors,Easy to use low - cost single chip microcomputer.



- easy to develop: since the link layer is fully integrated on the module, it is very easy to develop.Automatic re-issuance,Automatic detection and redistributing of lost packets,The time and frequency of redistribution can be controlled by software automatically storing the automatic response function of packets that do not receive the response signal,Upon receipt of valid data,Module automatically sends response signal,No additional programming carrier detection - fixed frequency detection 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 jump setting and six-way receiver address can be set simultaneously,Optional open receiving channel standard pin dip2.54 mm spacing interface,Easy to embed applicat
