All I found in my brief search was a photo that shows that the connections are in the lower left corner of the PC board.
From what I can tell the devices with the pins in this corner use an HD44780 compatible controller and are therefore compatible with the LiquidCrystal library. The problem is that although the pin numbers are consistent with other devices, the order of the pins on the PC board is not. In addition it seems that the boards with the pins in this corner may not be consistent with others by a different manufacture either.
So your real problem is to identify the pins, once you do that you can use the LiquidCrystal library.
