Arduino Pro Mini + Servo + Accelerometer Setup Help

I want to run an Arduino Pro Mini board (for its size) with an MPU6050 (accelerometer) . I want the MPU6050 to make a servo spin. I'm going to try to run them from a 5v/1A boost board which itself is powered by a 3.7V LiPo.

The Pro Mini boards come in 3.3v and 5v power/logic. Either one, not both. The MPU6050 needs 3.3v power, the Mini can only take 3.3v power/logic and the servo is going to need 5v power.

So there is going to be a lot of logic shifting and power regulating which is a nuisance.

Do you have any advice for me on the best way to set this up?
