Note: Before running the procedure, pls install the corresponding computer system driver. Drivers: directly from the chip manufacturer: WCH 340 product home page: http://www.wch.cn/product/CH340.html http://www.wch.cn/download/CH341SER_LINUX_ZIP.html (linux should operate fine without the driver) http://www.wch.cn/download/CH341SER_MAC_ZIP.html http://www.wch-ic.com/download/list.asp?id=127 (windows) http://bit.ly/2pMF4in ATmega328 Microcontroller Microcontroller ATmega328P-AU Fully Compatible to Arduino Nano V3.0 ATmega328P-AU Input Voltage (recommended) 7V-12V;Input Voltage (limits) 6V-20V Bootloader installed, ready to upload sketches from Arduino software Analog Input Pins 8 Operating Voltage 5V DC Current per I/O Pin 40 mA DC Current for 3.3V Pin 50 mA Digital I/O Pins 14 (of which 6 provide PWM output) Flash Memory 32 KB (ATmega328) of which 2 KB used by bootloader SRAM 2 KB EEPROM 1 KB Clock Speed 16 MHz Cable Length:245mm Dimention:Approx. 45x17x19mm Color:Blue(as the picture shows) Package: 1 x Nano V3.0 ATmega328P Arduino Compatible Board 1 x Mini USB Cable See more

Usage:1. download arduino IDE, (download address: http://arduino.cc/en/Main/Software; 2. Download the USB chip driver, (download address :http://wch.cn/downloads.php?name=pro&proid=65); 3. Plug in the NANO development board, the driver will be automatically installed; 4. Open the IDE of arduino, select NANO for the board, and COM3 for the serial port, and click Download; 5. It is best to select the routine programme that comes with the arduino, burn it in. Specification:The Nano can be powered via the Mini-B USB connection, 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.Usage: The Nano is 100% compatible with Arduino, with the same chips ATmega328P and CH340 with the official version. Small Arduino UNO Board:It is a smallest, complete and breadboard friendly board. It has everything that Arduino/Genuino UNO has (electrically) with more analog input pins and onboard +5V AREF jumper.More Breadboard Space:Nano's got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). If you need an older driver, pls get it from GitHub—please read the link that follows immediate. http://sparks.gogo.co.nz/ch340.html; More detals on how to use it please refer to: http://audiodiwhy.blogspot.com/2018/05/one-cheap-arduino-nano-clone-o-plus-one.html. NOTE: If you want it to work on a Mac, please install the diver from this: https://drive.google.com/drive/folders/1phezjJtQW0vav34RoivsAzjF0ugmqjgn?usp=sharing; If you want it to work under Windows 10, You must turn off automatic updates before you install the driver, please install the diver from this: https://drive.google.com/drive/folders/1tl6sVGVduyH1JHfaYdMqeMGKdo-rg3im?usp=sharing.
