So if you&#8217;re not getting their hardware, drop them a donation &#8211; the link is easy to find on their download page (link below).<\/p>\n<p>&nbsp;<\/p>\n<h3>Why the Nano, or Arduino in general?<\/h3>\n<p>Price issues aside, I&#8217;m one of those individuals that doesn&#8217;t like taking on a fly with a sledgehammer &#8211; not when a \u00a31.5 flyswatter will do.<\/p>\n<p>Also, while most of the hardware addons have had their Arduino libraries ported to RPi, for example, there&#8217;s\u00a0 beauty in using a piece of hardware on the platform it was developed for, with the libraries that were written for it.<\/p>\n<p>Also, no OS installation, no SD cards, etc. So if your project is not overly complicated (needs network \/ server, etc), you&#8217;re probably better off with the old, smart KISS -move.<br \/>\n(&#8220;Keep It Simple, Stupid&#8221;&#8230;)<\/p>\n<p>&nbsp;<\/p>\n<h3>Getting that thing running&#8230;<\/h3>\n<p>First you want to get two things before you plug in that thing (and see if it even works):<\/p>\n<ul>\n<li>get the <a href=\"https:\/\/www.arduino.cc\/en\/Main\/Software\" target=\"_blank\">official Arduino Software<\/a><\/li>\n<li>get the driver for your CH340-based board &#8211; yes, the driver zip is called <span id=\"spantitle\">CH341SER.ZIP (not &#8220;340&#8221;)<\/span>.<br \/>\n<a href=\"http:\/\/www.wch.cn\/download\/CH341SER_ZIP.html\" target=\"_blank\">Official link<\/a> or <a href=\"http:\/\/elmeranta.fi\/blog\/wp-content\/uploads\/2016\/03\/CH341SER.zip\" target=\"_blank\" rel=\"\">local mirror on this server (win)<\/a> (newest as of 8.3.2016, driver dated <strong>3.4.2014<\/strong>)<br \/>\n(<a href=\"http:\/\/www.wch.cn\/download\/CH341SER_MAC_ZIP.html\" target=\"_blank\">MAC<\/a> and <a href=\"http:\/\/www.wch.cn\/download\/CH341SER_LINUX_ZIP.html\" target=\"_blank\">Linux<\/a> versions)<\/li>\n<\/ul>\n<p>As usual with Strange Little Devices from Far Away Lands &#8482;, you&#8217;re better off installing the drivers and software before plugging in anything. My personal installation order was &#8220;Chinese first, official for dessert&#8221;.<\/p>\n<p>If everything goes as planned, the clone will light up that bright red led as soon as you plug it in and Windows (or your chosen OS poison) will churn a bit and recognize the device. It seems to depend a lot on your computer and network speed if you let Windows do it automatically (my old C2D laptop on ADSL took nearly 5 minutes while the faster i5 laptop on dedicated 100mbit network took 10 seconds, go figure).<\/p>\n<p>&nbsp;<\/p>\n<p>Easiest way to test the device is to load up an example sketch (= piece of source code) from the example library under the File -menu in the Arduino software.<br \/>\n<em><strong>Just remember to choose the board and COM-port from the Tools \/ Board &amp; Port -menus first!<\/strong><\/em><\/p>\n<p>When you have the code (I use &#8220;blink&#8221; under &#8220;01. Basics&#8221; as a test sketch), just hit CTRL+R to compile \/ verify it or CTRL+U to upload it. Presto!<\/p>\n<p><em>If you ordered a &#8220;solder-it-yourself&#8221; -type board like me, you can do the connection and example sketch testing before you whip out your soldering iron and put the board together.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>If no presto, check what you did, make sure USB wire, etc are working and if you still have problems you might want to think about complaining to the seller &#8211; the cheap clones are known for cheap quality and some of them *do* fail or are DoA. At this price you&#8217;re usually better off ordering two or three from different sources.<\/p>\n<p>&nbsp;<\/p>\n<p>So what to do with it then?
