Key features

• •★Matters Need Attention: 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.
• •★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.
• •★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
• •★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).
