The unit arrived on time with a bunch of other goodies. This board seems to be an older version of this board (v1 yet there is now v3 out there) but it works just fine on I2C address 0x3F. When inspecting the board, I instantly noticed the I2C board was soldered too closely to the LCD PCB and was ultimately angled. Next, the LCD has metal tabs that hold it together yet the I2C PCB was touching one of these tabs that risked a short. I had to fold over one of these twisted tabs to avoid issues.

The display is a standard LCD device with the addition o a serial "backpack" on the back. it works well once you find the correct drivers. The problem is the driver information is not included with this device or on the web site. Neither is the manufacture. You have to match the backpack to an image for an identical product to determine the source, the drivers required, their location, wiring details and address of the backpack. Once you master these items the device works very well.

I ordered two of these for projects I was working on. The LCD itself is good but the I2C adapter is mounted at an angle. This is required to give necessary clearance for the screen mounting tabs commming through the PCB. On one of the units the I2C adapter didn't have enough clearance and the aforementioned screen mounting tabs was shorting two pins on the adapter board. Also these it would be nice if the I2C address was provided. Apparently there are only a few addresses for these things but I had to try a few times before I could talk to it. Other than that, once you ensure no pins shorted and you can communicate with it, it's fine.

Got this and hooked it up right away. Works great! Just make sure you're using the right address (usually 0x27 or 0x3F) as some displays use one or the other.

If you're Looking for a Simple way to use a LCD and not have to research a whole lot on how to program it and what the pins do and everything, this is an awesome option. Uses the I2C protocol over two wires and couldn't be easier.
