Colour Name:RFfnano board 2pcs RF-Nano: Note: Please use Arduino IDE 1.8.6 or higher version, First, install the CH340 driver,then follow this selection path in Arduino IDE：Tools - Board“Arduino Nano” Processor “ATmega328P", otherwise you'll find that you can't burn any program. Please refer to our github link,it can help you to slove any problem. "The Nano Board has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328P provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The ATmega328P also support I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus. To use the SPI communication, please see ATmega328P datasheet.
