MOSI: (Master Out Slave In) It is SPI input to the module.SCK: (Serial Clock) it accepts clock pulses provided by the SPI bus Master.When this pin goes low, the module begins listening on its SPI port for data and processes it accordingly. CSN: (Chip Select Not) is an active-LOW pin and is normally kept HIGH.When selected the module will either transmit or receive, depending upon which mode it is currently in. CE: (Chip Enable) is an active-HIGH pin.Remember connecting it to a 5V pin will likely destroy your nRF24L01+ module! So, you can connect it directly to the 3.3V pin of our Arduino. It is placed inside a square for easy identification. ![]() The features enable significant improvements of power efficiency for bi-directional and uni-directional systems, without adding complexity on the host controller side. Enhanced ShockBurst™ enables the implementation of ultra low power, high performance communication with low cost host microcontrollers. It uses Enhanced ShockBurst™ for automatic packet assembly and timing, automatic acknowledgement and retransmission of packets. ![]() The module is configured and operated through a Serial Peripheral Interface (SPI).Each channel can have up to "6 addresses or 6 data pipes" or in other words, each unit can communicate with up to 6 other units at the same time (1:6 star networks). The module has 125 independent RF channels giving the possibility to have a network of "125 independently working modems" in one place.The Range of this module as per its datasheet is 100m but it works up to 50 to 60 meters in real world conditions.It has an integrated (on chip) voltage regulator. All other pins on this board are 5V tolerant making it easy to connect to an Arduino without using a logic level converter. Operating voltage is between 1.9V to 3.6V.The power consumption of this module is just around 12 milliamps during transmission (TX) which is even lower than a single led. The high air data rate combined with two power saving modes makes the nRF24L01 module very suitable for ultra low power designs. It has 2 power saving modes operating at 22uA Standby-I mode and 900nA in power down mode - which makes these modules suitable for battery operated nodes. Power consumption? This module is designed for ultra low power wireless applications.Data transfer rate is between 250kbps to 2Mbps baud. ![]()
