![]() If you use an Arduino Mini board, you will have to use an external voltage regulator as the board does not have a 3.3V output. The CE and CSN pins are connected to any digital pin of the Arduino. MISO – to 12 for Arduino Uno, Nano, and 50 for Arduino Mega. The SCK pin should be connected to pin 13 for Arduino Uno, Nano, and 52 for Arduino Mega. The MOSI pin from the nRF24L01 board connects to pin 11 for Arduino Uno, Nano and to 51 for Arduino Mega. Using YourDuinoRobo1, which has an additional 3.3V regulator.Designing a separate board, installing the nRF24L01, and adding 1 and 10 uF capacitors to it.It is better to choose a capacity of 10 μF or more. Connecting a capacitor to the chip to 3, 3 V(+), and GND (-) ground.There are several methods to solve this problem: For the above types of boards, a small current of 50mA is applied to the pins. Usually, such difficulties appear when using Arduino Uno, Nano, Mega boards, i.e., those with insufficient power. This can cause interference that interferes with stable operation. MISO – data reception to the controller ĭuring the microcontroller start-up, you might have some problems, which are caused by the fact that the 3.3V supply module is not provided with the right current.MOSI – data transfer from the controller.SCK – SPI clock, the maximum value is 10 MHz.In this case, the device responds to SPI commands CSN – switching on the low level of the chip.The device’s input, which is connected to the board, must consume a current not exceeding 10 mA. In addition to the power outputs, the signal lines can be connected to contacts with a supply voltage of 5 V. The receiving device must give a response to data reception, thus confirming the feedback. The Enhanced ShockBurst protocol is responsible for stable and reliable data transmission and reception. RX mode current consumption is higher than TX mode. The module has 4 operating modes – Power Down, Standby, RX mode, TX Mode. That is, zero corresponds to a frequency of 2.4 GHz, channel 83 – 2.483 GHz. The frequency range in which communication takes place is 2.4 – 2.483 GHz. The channel number determines the operating frequency of the module. The nRF24L01+ board includes a frequency synthesizer, demodulator, amplifiers, and other components. Various elements of the smart home – alarms, temperature control, and other functions.nrf24l01 can be successfully applied in the following areas: One of the most important components of IoT projects is communication. The SPI interface can be used to configure the protocol, set the output power, and establish data exchange channels. All necessary elements and a connector plug are located on the chip. The module is based on nRF24L01+ manufactured by Nordic Semiconductor. The range of communication up to 328 ft.Operating temperatures from -40F to 185F, storage temperatures from -40F to 257F.Fully compatible with all standard nRF24L Nordic series as well as nRF24E and nRF240 series.Data transfer rates of 250 kbps, 1 Mbps, and 2 Mbps.Advanced ShockBurst hardware protocol gas pedal.In addition, the NRF24l01 radio module is cheap, so that it can be found in a wide variety of projects, from smart homes to various homemade robots. Up to seven devices can be interconnected to form a common 2.4 GHz radio network, with one module acting as master and the others as slaves. Multiple devices can be interconnected to transmit data over the radio link. The nRF24l01 is a highly integrated 2Mbit/sec low power (ULP) chip for the 2.4 GHz band. The NRF24l01 is perfectly suited to create distributed systems with sensors and controllers separated by up to 328 ft. This is why it is so important to choose the right platform for communication between the modules. You cannot create a really interesting project without creating communication between the different parts of the system. 11 Conclusion Description of the nRF24L01 Wireless Module
