2.4Ghz ISM band, license free, multi point short range NRF24L01 + 2.4G wireless module

Low-cost short-range NRF24L01 + 2.4G wireless module

Description:
NRF24L01 + 2Mbit / s 1Mbit / s 250Kbit / s transfer rate three options



Parameters:
1) 2.4Ghz ISM band, license-free worldwide use of open
2) The maximum operating rate of 2Mbps, efficient GFSK modulation, anti-interference ability, particularly suitable for industrial control applications
3) 126 channels, multi-point communications and frequency hopping to meet thecommunication needs
4) Built-in CRC error detection hardware, postal address, and multipoint control
5) low-power 1.9 - 3.6V, standby mode state is 22uA; 900nA Power-down modeis
6) Built-in 2.4Ghz antenna, compact 15mm X29mm
7) The module can be software based address, only the address of the machineonly when the received output data (interrupt instructions provided), can be directlyconnected using a variety of single-chip, software programming is very convenient
8) Built-in special voltage regulator circuit, using a variety of power supplyincluding DC / DC switching power supply has good communication results
9) DIP spacing standard interfaces for embedded applications
10) Work in Enhanced ShockBurst with Automatic packethandling, Auto packet transaction handling, with optional built-in packet response mechanism, greatlyreduce the packet loss rate.
11) with 51 computers connected P0 port when the need to add 10K pull-upresistors, do not connect with the rest of the mouth.
12) other series of microcontrollers, if it is 5V, please refer to the MCU IO portoutput current size, if more than 10mA, requires a 10K resistor in series.
