Access the Linkit Smart 7688 Duo pins' with mraa library

I saw in the mraa page that this library can be used with Linkit duo ( but the pinout is diferent between Linkit Smart 7688 and Linkit Smart 7688 Duo and they doesn´t inform in this page about it. So my question is how can i access the Linkit Smart 7688 pins’ with the mraa library?
I’ve used the mraa library with Linkit Smart 7688 in a previous project. However, due to availability problems, we plan to adapt this project to Linkit Duo.
Can someone help me?
