Arduino Nano with CH340 Uploader – Micro USB

Nano (Arduino Nano Compatible Atmega328p+CH340) is based on famous Arduino platform and does all the functions of Uno, but with a smaller footprint.This development board provides small plate with the same powerful microcontroller. It is compatible with Arduino and ideal for fast prototyping and easy integration. It’s vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good. The board equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 . It lacks only a DC power jack and works with a Micro USB cable instead of a standard one.

The board can be powered via the Micro-USB connection, 6-12V 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.The size of board is only 43 mm x 18 mm, it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory. It can be programmed directly from the Arduino IDE, using the Micro USB connection.

Note: This board is a 100% compatible clone version with same design as Arduino Nano. It is not the original version which is made in Italy. CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.

Watch a video walkthrough of this process

we’ll show you how to install CH340 drivers on multiple operating systems if you need them. The driver should automatically install on most operating systems. However, there is a wide range of operating systems out there. You may need to install drivers the first time you connect the chip to your computer’s USB port or when there are operating system updates.

Windows

1. Download the Windows CH340 Driver
2. Unzip the file
3. Run the installer that you unzipped
4. In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.
