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.
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)..
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..
