I don't know.
I haven't purchased any and as I said I've sent a query to someone.!
Please feel free to not use any of the information if you feel it will 
comprimise your preferences.

Do you actually think I'd publish an article, demonstrate something and 
send a post showing what I used and hide that it didn't work ...please

Do they work??? ... same answer as above Volker.!!

They are a I2C interface.
I put this into Google      liquidcrystal_I2C     and got 38,000

However this link was for Colin as we were the ones having the
