Mini NRF24L01 SMD Wireless module
Market similar to the smallest completely replace the inline
module.
The NRF24L01 is a monolithic transceiver chip that operates in the
world's common ISM band of 2.4-2.5GHz. The wireless transceiver
includes: Frequency Generator Enhanced SchockBurstTM Mode
Controller Power Amplifier Crystal Amplifier Modulator Demodulator
Output Power Channel Selection and Protocol The setting can be set
to extremely low current consumption via the SPI interface. When
the transmit power is 6dBm in transmit mode, the current
consumption is 9.0mA. The accept mode is 12.3mA and the current
consumption mode is lower in standby mode. Ball open ISM band, the
maximum 0dBm transmit power, free license to use. Support six
channels of data reception
1. Low operating voltage: 1.9 ~ 3.6V low voltage operation
2. High rate: 2Mbps, because the air transmission time is very
short, greatly reducing the collision in the wireless transmission
(software set 1Mbps or 2Mbps air transfer rate)
3. Multi-frequency: 125 frequency points to meet the needs of
multi-point communication and frequency hopping communication
4. Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm
(including the antenna)
5. Low power consumption: When working in answer mode
communication, fast air transmission and start time, greatly
reducing the current consumption.
6. Low application cost: NRF24L01 integrates all the high-speed
signal processing related to the RF protocol, such as: automatic
retransmission of lost data packets and automatically generate
response signals, NRF24L01 the SPI interface can use the
microcontroller's SPI interface to connect or use the
microcontroller I / O port to simulate, the internal FIFO can be
with a variety of high and low speed microprocessor interface, easy
to use low-cost single-chip.
7. Easy to develop: As the link layer is fully integrated on the
module, very easy to develop. Automatic retransmission function,
automatic detection and retransmission of lost data packets,
retransmission time and the number of retransmission software
control can automatically receive the response signal does not
receive the packet automatic response function, after receiving the
valid data, the module automatically sends a response Signal, no
additional programming Carrier detection - Fixed frequency
detection Built-in hardware CRC error detection and
point-to-multipoint communication address control Packet
transmission error Counter and carrier detection function can be
used for frequency hopping settings can be set at six simultaneous
receive channel address, can be selective The open receive channel
standard pin Dip2.54MM pitch interface for easy embedded
applications.
