they are using a 3.3 V logic shifter? What is that,
I why cant I just use the 3.3V pin on my Arduino Uno?
FETs = Transistors.A lot of ebay auctions say "Arduino Compatible". In many cases that just means that an arduino and it can be hacked together in such a way that it works. In many cases that hacking is just a level shifter, or getting a 3.3v arduino.You will need the (logic) level shifter otherwise you will most likely damage the display.
FETs?The ebay add said its Arduino compatable, but I still need a logic shifter then?Thanks
