Watch out that many of those are 3.3v circuits, so you need a level
converter as well.  i have been using these:

bi-directional 4 channel 5v-3.3v level converters, it even includes the
3.3v regulator.

there will be other listings selling smaller quantities, look for the
double-arrow logo on the back to easily pick the right one
