Description

NRF24L01 2.4 GHz wireless transceiver module

The nRF24L01 is a wireless transceiver module, meaning each module can both send as well as receive data. They operate in the frequency of 2.4GHz, which falls under the ISM band and hence it is legal to use in almost all countries for engineering applications. The modules, when operated efficiently, can cover a distance of 100 meters (200 feet) which makes it a great choice for all wireless remote controlled projects. ( find out a wide range of IoT And Wireless products  at solicstores.in)

The module operates at 3.3V hence can be easily used with 3.2V systems or 5V systems. Each module has an address range of 125 and each module can communicate with 6 other modules hence it is possible to have multiple wireless units communicating with each other in a particular area. Hence mesh networks or other types of networks are possible using this module.

nRF24L01 Pin Configuration

NRF24L01

Pin Number Pin Name Abbreviation Function
1 Ground Ground Connected to the Ground of the system
2 Vcc Power Powers the module  using 3.3V
3 CE Chip Enable Used to enable SPI communication
4 CSN Ship Select Not This pin has to be kept high always, else it will disable the SPI
5 SCK Serial Clock Provides the clock pulse using which the SPI communication works
6 MOSI Master Out Slave In Connected to MOSI pin of MCU, for the module to receive data from the MCU
7 MISO Master In Slave Out Connected to MISO pin of MCU, for the module to send data from the MCU
8 IRQ Interrupt It is an active low pin and is used only if the interrupt is required

How to Use the NRF24L01

The NRF24L01 module works with the help of SPI communications. These modules can either be used with a 3.3V microcontroller or a 5V microcontroller but it should have an SPI port. The circuit diagram shows how the module should be interfaced with a microcontroller.

NRF24L01

The SPI Pins (MISO<MOSI and SCK) are connected to the SPI pins of the Microcontroller and the signal pins (CE and CSN) are connected to the GPIO pins of the MCU.
