Re: Prewired 16x2 blue display

I have bought two of those displays from them, and neither worked. The larger displays I have (5 from different sources) do not use the same pin out as the regular ones. The last two pins are reversed, and if you power on wired wrong it will destroy the display.

Yes there are somewhat larger common 16x2 displays. I can't speak to 'direct' replacement, (not interested in doing that homework) but these have I2C modules and 6800 parallel library support.

Look at the datasheet and see if the size is what your after.  The rest should be simple software changes, if needed at all.
