Arduino RF-NANO Integrated with NRF24L01 Wireless Module

DESCRIPTION : The NRF24LO1 chip is integrated on the RF NANO, which makes it have unlimited transceiver functions, which is equivalent to combining ordinary Nano board and NRF24LO1 module into one, which is more convenient to use and small in size. The RF-NANO has exactly the same pins as the regular nano board, which is easy to transplant. Product parameters: Introduction of the processor: Arduino RF-NANO microprocessor is ATmega328 (Nano3.0), with USB-Micro interface, and has 14 digital input/output (6 of which can be used as PWM output), 8 analog input, a 16MHz crystal oscillator, a USB Micro port, an ICSP header and a reset button. Processor: ATmega328 Working voltage: 5V input voltage (recommended): 7-12V Input voltage (range): 6-20V Digital IO pins: 14 (of which 6 are used as PWM outputs) (D0 ~ D13) Analog Input Pins: 6 (A0 ~ A5) Io pin DC current: 40mA Flash memory: 32KB (of which 2KB is used for bootloader) SRAM: 2KB EEPROM: 1KB (ATmega328) USB to serial port chip: CH340 Working clock: 16MHz Power supply: Arduino RF-Nano power supply mode: Micro-USB interface power supply and external fin connected to 7~12v external DC power supply Memory: ATmega328 contains 32KB of Flash on the chip, of which 2KB is used for Bootloader. Also 2KB SRAM and 1KB EEPROMo InputOutput: 14 digital input and output ports: the working voltage is 5V, and the output and access limit current of each channel is 40mA. Each channel is configured with a 20-50K ohm internal pull-up resistor (not connected by default). In addition, some pins have specific functions. Serial port signal Rx (No. o), TX (No. 1): provide the serial port receive signal of TTL voltage level, and connect to the corresponding pin of FT232RI. External Interrupt (No. 2 and No. 3): Trigger the interrupt pin, which can be set as rising edge, falling edge, or both. Pulse Width Modulation PWM (3, 5, 6, 9, 10, 11): Provide 6 8-bit PWM outputs. SPI ( 10(SS), 11(MOSI), 12(MISO), 13(SCK)): SPI communication interface. LED (No.13): Arduino is specially used to test the reserved interface of LED. When the output is high, the LED is turned on, otherwise the LED is turned off when the output is low. 6 channels of analog input A0 to A5: each channel has a resolution of 10 bits (that is, the input has 1024 different values), the standard input signal range is 0 to 5v, the upper limit of the input can be adjusted by AREF. In addition, some pins have specific functions. TWI interface (SDAA4 and SCL A5): support communication interface (compatible with I2C bus).
