Product features:
1. The improved version adopts the ATMGEA328P-AU chip in QFP32 package, which can reduce the development cost while ensuring the product function;
2. The board integrates a NRF24L01+ chip, which makes it have unlimited transceiver functions;.
3. Nano development board and a NRF24LO1 module into one, more convenient to use, small size;
4. The pins are exactly the same as the common Nano boards, making it easy to port;
5. There are two kinds of interface options, USB-Micro and Type-C interface can be selected, can be connected to most of the products on the market to realize the interface power supply.
Product Description.
RF-NANO board integrated NRF24L01 + chip, making it has unlimited transceiver function, equivalent to a Nano development board and a NRF24LO1 module into one, more convenient to use, small size. The pins are exactly the same as those of common Nano boards, making it easy to port.

Inputs and outputs.
14 digital inputs and outputs: operating voltage is 5V, each one can output and access a limit current of 40mA. each one is configured with 20-50K ohm internal pull-up resistors (not connected by default). Besides, some pins have specific functions.
Serial signals Rx (No. 0), TX (No. 1): Provide serial receive signals at TTL voltage level, connected to the corresponding pins of FT232RI.
External Interrupt (No. 2 and No. 3): Trigger interrupt pin, can be set to rising edge, falling edge or simultaneous trigger.
Pulse Width Modulation PWM (3, 5, 6, 9, 10, 11): Provides six 8-bit PWM outputs.
SPI (10(SS), 11(MOSI), 12(MISO), 13(SCK)) : SPI communication interface.
LED (No. 13) : Reserved interface specially for testing LED, LED is lit when output is high, and vice versa LED is off when output is low.
6 analog inputs A0 to A5: each with 10-bit resolution (i.e., 1024 different values for the inputs), the default input signal range is 0 to 5V, and the upper input limit can be adjusted by AREF. Besides, 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 signal.
Reset:Reset the microcontroller chip when the signal is low.
Communication Interface.
Serial Port: The built-in UART of ATmega328 can realize serial communication with external through digital ports 0(RX) and 1(TX).
