easy connection, works as expected

I am just using this as an LCD display, so the cable it shipped with isn't used. To use it, just connect VCC/GND, and SDA and SDL to an Arduino. Download the library in the dfr0154.zip from the link above, and voila. You are up and running. Mine shipped with the i2c address set at 0x27. I've seen some LiquidCrystal_i2c libraries' examples defaulting to 0x20. If yours doesn't work, try 0x27 for the address. I did also try to run it at 3.3v and 5v, both work fine. Although at 3.3v, the pot at the back has to be adjusted all the way to the left, and even then the contrast is not great. At 5v it is beautiful.

Works great

I have purchased several of these displays with I2C, I find them easy to write to and only need two wires!
