Hi guys, I am going to build a breakout board for my 20x4 LCD screen, and I was wondering if there is any advantages over using 4bit or 8bit mode. I have always used 8bit mode. I would think that 8bit mode is faster as you transferring 8bit instead of 4.

Yes, 8 bit mode would be faster - in 4 bit mode, you have to transfer the low and high nibble of each byte separately while as in 8 bit mode, you transfer a whole byte in each transaction.
Will you be using a separate device (shift reg or similar) in between the Netduino the LCD and if so, may I ask which?
