I found these Arduino Uno clones (link) on Ali Express for £2.16 each with free shipping from china, I can’t even get Diavolino for that little (Also a Diavolino needs a RS232 / FTDI or something as well).
These clones come with something different, rather than the usual FTDI they come with a CH340G / CH341G Serial/USB chip.
Mac OSX doesn’t have the drivers by default (Windows 7 finds it in the driver database).
Download the driver
You should be able to get the driver from the Chinese company that developed it: here. It took forever to download, so I put up a copy Here – CH341SER_MAC.
Install it
- Download the driver
- unzip it
- Open the folder
- Run installer found in that folder
- If asked to restart, do not restart just yet.
- This next step is only needed if you are on OS-X Yosemite. possibly needs done on other versions:
- Open Terminal Application, then run e this:
sudo nvram boot-args="kext-dev-mode=1"
- Now restart your Mac
Not bad to let you use a £3 Arduino UNO clone!
