DIP24L01 / SMD24L01:
RF24L01 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 amplifier crystal amplifier 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, license-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 collision phenomena (software settings 1Mbps or 2Mbps air transmission rate)
(3)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.
(6)Low application 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)facilitate the development: the link 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 valid 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 applications.
