The Odroid XU4 board has two GPIO headers, the first with 30 pins and the second with 12. Both headers have pins with a 2 mm spacing.
Which, as you can see, creates a compatibility problem with the Raspberry Pi standard, which has widely imposed the 2.54 mm-pitch 40-pin GPIO header. Another problem, the XU4 GPIO headers deliver a voltage measured at 1.8V, which is insufficient for lots of devices operating generally with either 3.3 or 5V.
Fear not, the designers of the XU4 board have thought of everything – namely a shield created especially to ensure their latest baby is fully compatible with Odroid C1 and Raspberry Pi 2 B model (or almost).
The Odroid XU4 shield converts the 42 1.8V GPIO pins into a single GPIO 2.54 mm-pitch 40-pin header, and has a switch so you can choose between a 3.3V and 5V mode. The added bonus is the shield’s “sea of holes”, in other words a small prototyping area so you can benefit immediately from your XU4’s new-found compatibility.
We’ve spared a thought for all those wishing to take their analysis of the Odroid Shifter Shield a little further with these two technical schematics:
