  • I am a relatively new Arduino user - have been playing for about a year now, but have only done a handful of small projects. I’ve recently purchased this 5v pro mini and a triple access accelerometer ( The accelerometer is a 3.3v piece, and this pro mini is a 5v. If I want to use the two together do I need to get a 3.3->5v logic controller (for example or can I simply build myself a circuit that has a 3.3v power source? I was planning to design this into a project that would have a custom PCB, and if I can simply plan in a 3.3v regulator, I may do that.

    Happy to supply more details if more info is needed.
