I think the voltage may drop too low? Does anybody know this problem and maybe some solution?

Digital I/O pins 8-13. In this group, the shield in its default configuration uses pins 9 and 10 for INT and SS interface signals.
Ah okay. So it should work if i connect these two pins to other pins for one device and change the pin assignments in the library, right?
