16x2 LCD i2c backpack pinouts

by TimPelling on Tue Jan 01, 2013 2:08 am

I want to plug the backpack into a breadboard - can you please indicate which of the raspberry pi's GPIO pins are used by the backpack? (It would be useful to include this information in the tutorial).

Both the product description and the tutorial say:
a Pi plate that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Pi!

Ok, good start - and Happy New Year ;o)

Which voltage and ground pins does it use on the GPIO header?

(Sorry - could have worked this out for myself if I'd not soldered it together before thinking about it)
