RF-Nano works with ATMEGA328P Nano V3.0 integrated NRF24L01 wireless CH340 serial module.

Features:
1. The enhanced version uses the ATMGEA328P-AU chip packaged in QFP32, which ensures the product functionality while reducing development costs.
2. The NRF24L01 + chip is integrated on the board, achieving unlimited transmission and reception functions.
3. The nano development board and the NRF24LO1 module are integrated together, making it more convenient to use and smaller in size.
4. The pins are the same as the ordinary nano board, making it easy to plant.
5. There are two interface options, USB-Micro and Type-C, which can be connected to most products on the market to achieve interface power supply.

Product introduction:
The RF-NANO board integrates NRF24L01+ chip, which has unlimited transceiver functions, equivalent to combining a Nano development board and an NRF24LO1 module, making it more convenient to use and smaller in size. The pins are the same as those of ordinary Nano boards, making it easy to plant.

Parameters:
Processor introduction:
The module's microprocessor is ATmega328 (Nano3.0), with USB-Micro/Type-C interface, 14 digital input/output ports (6 of which can be used as PWM output), 8 analog inputs, 16MHz crystal oscillator, USB port, ICSP header, and reset button.
Processor: ATmega328
Working voltage: 5V input voltage (recommended): 7-12V input voltage (range): 6-20V
Digital Lo Pin: 14 (of which 6 are used as PWM output) (D0 ~ D13)
Analog input pins: 6 (A0 ~ A5)
IO PIN DC current:
Flash memory: 32KB (2KB for bootloader)
SRAM: 2KB
EEPROM: 1KB (ATmega328)
USB to Serial Chip: CH340
Working Clock: 16MHz
Power Supply:
Power Supply Method: USB Connect Power Supply, and External Vin Connect to an External 7-12V DC Power Supply
Memory:
ATmega328 includes a 32KB Flash chip, of which 2KB is used for bootloader. In addition, there are 2KB SRAM and 1KB EEPROM.
Input Output:
14 digital input/output ports: The working voltage is 5V, and each channel can output and access a maximum current of 40mA. Port Each circuit has an internal 20-50K ohm pull-up resistor (default not connected). In addition, some pins have specific functions.
Serial port signal RX (No. 0) and TX (No. 1): provide the serial port receive signal with TTL voltage level, connected to the corresponding FT232RI pin.
External interrupt (No. 2 and No. 3): trigger interrupt pins, which can be set to rising edge, falling edge, or trigger simultaneously.
PWM pulse width modulation (3, 5, 6, 9, 10, 11): provide 6 8-bit PWM.
SPI (10 (SS), 11 (MSI), 12 (miso), 13 (SCK)): SPI communication interface.
LED (No. 13): A reserved interface designed exclusively for testing. When the output is high, the LED is on, and when the output is low, the LED is off.
6 analog inputs A0 and A5: Each channel has 10-bit resolution (ie, 1024 different input values), and the default input signal range is 0 to 5V. The upper limit of the input can be adjusted via aref. In addition, some pins have specific functions.
Twi interface (A4 SDA and A5 SCL): Support communication interface (compatible with I2C bus)
Aref: Reference voltage for analog input signals
Reset: When the signal is low, reset the microcontroller chip
. Communication interface:
Serial port: The built-in UART of ATmega328 can communicate with external devices through digital ports 0 (RX) and 1 (TX).
