Brand Name: wireless module

Model Number: NRF24L01 NRF24L01 wireless module: NRF24L01
Place of Origin: China (Mainland)
Notice: The new tracking number for China Post Ordinary Small Packet Plus only can track it have been ship out of China, not more Tracking information ,even it arrived or not . Please do not freeloaders,if you can not accept without more tracking information . Please choose China Post Air Mail if you want a full tracking info. Tracking info of  China Post Ordinary Small Packet Plus can be check here : www.17track.net/en    Provide tracking numbers over>7usd, free ship by China post Registered air mail, mixed items OK in my store! NRF24L01 is a work in the 2.4-2.5GHz worldwide ISM band single-chip transceiver, wireless transceiver, including: the frequency generator the enhanced SchockBurstTM mode controller power ampfier crystal ampfier modulator demodulator output power channel selection and protocol set by the SPI interface to set a very low current consumption, lower current consumption mode 12.3mA Power-down mode and standby mode when in transmit mode emission power 6dBm when current consumption is 9.0mA acceptance model. Ball to open ISM band maximum 0dBm transmit power, cense-exempt use. The open 100 meters! Support six channels of data reception (1) low operating voltage: 1.9 ~~ 3.6V low-voltage (2) high-rate: 2Mbps, air transmission time is very short, greatly reducing the wireless transmission of colsion phenomena (software settings 1Mbps or 2Mbps air transmission rate) Multi-frequency points: 125 frequency points, to meet the multi-point communications and frequency hopping communications needs 4 ultra-compact: built-in 2.4GHz antenna compact 15x29mm (including antenna) (5) Low power consumption: when in answer mode communication, fast air transmission and start-up time greatly reduces the current consumption. Low appcation cost: NRF24L01 integrates all RF protocol high-speed signal processing section, such as: automatically resend lost packets and automatically generate an acknowledge signal, etc. the nRF24L01 The SPI interface can take advantage of the microcontroller hardware SPI port or microcontroller I / O port to simulate the internal FIFO can be used with a variety of low-speed microprocessor interface, easy to use low-cost microcontroller.

7 facitate the development: the nk layer is fully integrated in the module, very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost packets, the retransmission time and the number of retransmission can be software-controlled automatic storage is not received the packet of the response signal auto-answer, after the receipt of a vad data, the module automatically sends the reply fixed frequency detection signals without any additional programming Carrier Detect - built-in hardware CRC error detection and point-to-multipoint communication address control packet transmission error counter and carrier detection can be used for frequency hopping set can also set up six to receive the channel address, can have a choice of open receive channel standard the pin Dip2.54MM spacing interfaces for embedded appcations.     http://g003.a.acdn.com/kf/HTB1djUiHpXXXXXbXXXXq6xXFXXX9/201630778/HTB1djUiHpXXXXXbXXXXq6xXFXXX9.jpg?size=74462&;

Happy to be a Jule B customerFrom beginning to end the process of shopping with Jules B online can't be flawed. I shop from the other side of the world and don't feel the distance. The process, the paperwork and the follow up are all as good as they can be.

07 February 2012 Fantastic product and service with efficient swift delivery I ordered 13 handles in total from the Urfic range. The quality is superb and the delivery was both swift and well organised. The price was much cheaper than better known companies could offer and the service faultless. Would definately recommend and use again.
