Extending the LCD and Keypad from the i2c 16X2 RGB LCD Pi Pl

Post by [email protected] »

Hello,

I purchased an "RGB Negative 16X2 LCD+Keypad Kit for Raspberry Pi" from Adafruit product ID 1110.
https://www.adafruit.com/products/1110
I am more than satisfied with the product as it is everything I expected it to be. (Although I do have to trim the pot all the way to get the proper contrast - can this be adjusted?)

My question is ... What is the best way for me to extend the LCD and keypad buttons from i2c based Pi Plate? I wish to extend the LCD and keypads off of the RPi and on to the side wall of my enclosure. Unfortunately, I wish to do this without the larger bulky Pi Plate and without being constrained to the location/arrangement of the keys on the keypad (otherwise I could just use a ribbon cable to extend the GPIO connection.

Thanks in advance
Kevin

Well, the obvious answer is to just use a bunch of jumper wires. More involved would be to get a perf-board and an MCP23017 chip and lay everything out the way you want it. The schematics are available on the tutorial page:
