liudr:
... don't like that many jumper wires, messy.
I hear ya!
I hate that too... so I found a solution with the LCD-Keypad Shield...
All I did was removed the 16x2 LCD, removed the male pins and replaced with female pins...
... now I can plug my 20x4 LCD
... and probably ...(I have to take a look at the 128x64 datasheet)... too (?)..without modifications.
Anyhow, I might be safe Size-wise.
I am looking forward to that 128x64 then.
