Product Introduction:
The RF-NANO board integrates the NRF24L01+ chip, which endows it with unlimited transmission and reception capabilities. It is equivalent to combining a regular Nano board with an NRF24L01 module into one, making it more convenient to use and smaller in size. The pins of RF-NAN0 are exactly the same as those of common Nano boards, making it convenient for transplantation.

Processor Introduction:
The Arduino RF.NANO microprocessor is the ATmega328(Nano3.0), featuring a USB-Micro interface. It has 14 digital input/output ports (6 of which can be used as PWM outputs), 8 analog inputs, a 16MHz crystal oscillator, and a USB-Micro port. An ICSP header and a reset button.

Power supply:
The power supply methods for Arduino RF-Nano: power supply through the Micro-USB port and external vin connected to a 7-12V external DC power supply

Memory:
The ATmega328 includes 32KB of on-chip Flash, of which 2KB is used for the Bootloader. It also has 2KB of SRAM and 1KB of EEPROM.

Input/Output:

14-channel digital input and output ports: Working voltage is 5V, and each channel can output and connect a maximum current of 40mA. Each circuit is equipped with a 20-50K ohm internal pull-up resistor (not connected by default). In addition, some pins have specific functions.

Serial port signals RX(0), TX(1): Provide serial port receiving signals at TTL voltage levels, connected to the corresponding pins of FT232RI.

External interrupts (No. 2 and No. 3): Trigger interrupt pins, which can be set as rising edge, falling edge, or triggered simultaneously. Pulse Width Modulation PWM(3, 5, 6, 9, 10, 11): Provides 6 channels of 8-bit PWM output.

SPI(10(SS), 11(MOSI), 12(MISO), 13(SCK)):SPI communication interface. LED(No. 13):A reserved interface specifically designed for testing leds in Arduino. When the output is high, the LED lights up; conversely, when the output is low, the LED turns off.

6-channel analog input A0 to A5: Each channel has a resolution of 10 bits (i.e., the input has 1024 different values). The default input signal range is 0 to 5V, and the input upper limit can be adjusted through AREF. In addition, some pins have specific functions.

TWI interface (SDA A4 and SCL A5): Supports communication interface (compatible with I2C bus).

AREF: Reference voltage for analog input signals.

Reset: Reset the single-chip microcomputer chip when the signal is low.

Communication interface:
Serial port: The built-in UART of ATmega328 can communicate with the outside through the digital ports 0(RX) and 1(TX) via serial port.
