    I have the raspberry pi NB-IoT shield, and it works great!

    Now i want to make a “sandwich” with a raspberry pi 3 model b, the NB-IoT shield and the witty pi 2.

    The only issue i have, is that the physical pin #7 is used by both shields:

    NB-IoT schematic on the bottom of this page: https://sixfab.com/product/raspberry-pi-nb-iot-shield/
    WittyPi 2 schematic on page 32: http://www.uugear.com/doc/WittyPi2_UserManual.pdf

    The NB-IoT shield uses pin #7 for “1-Wire” while Witty pi 2 uses it to “detect the switching off signal”.

    It is possible to change the pin that the Witty pi 2 uses for this, but the guide they made does not work for me, and i’d rather not solder wires on the shields if i don’t have to.

    Guide: http://www.uugear.com/portfolio/change-the-pin-that-used-by-witty-pi/

    So, my question is, can the NB-IoT shield and Witty pi 2 work together sharing pin #7?
