Step 1: Arduino Nano Clones
Unfortunately an original Arduino Nano could cost you more plus shipping so it makes sense to search for an alternative source. There are also some chinese clones that are around five times cheaper, even with worldwide shipping.
But wait! There’s always a reason why a clone of something is cheaper than the original product. In this case there can be two pitfalls you need to know about.
Step 2: Original FTDI for Data Communication
Sometimes the FTDI chip which makes the USB communication possible is a counterfeit. This could cause problems when you install the official FTDI drivers and they just refuse to work.Usually there is no bootloader on the microcontroller. You need to upload it yourself and that means you need to have an appropriate programmer on hand.
Step 3: The Bad Part About Cheap Chinese Clones
So what makes this clone cheaper than the others? Well, most probably two things:
1.The headers are not installed.
2.It uses a different chip (CH340G) for serial-USB communication than the others.
The different serial chip on the other hand was something I was a little bit worried about but I’ve found my fears to be baseless. When I connected the board to the computer with a miniUSB cable it was instantly recognised by Windows as a virtual serial port.
Step 4: USB Not Recognizing
Step 5: Download Driver for CH340/CH341
The chipset used for USB-to-serial is CH340/CH341, drivers for which can be downloaded here.
Step 7: Unzip & Install the Driver
