The S9V11MACMA switching step-up/step-down regulator efficiently produces a finely adjustable output between 2.5 V and 9 V whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has a precision-adjustable low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge.

DRV8825 Stepper Motor Driver Module for Arduino. It allows you to control two drives, equipped with an XBee connector. DFRobot DRI0023

The S9V11F5S6CMA switching step-up/step-down regulator efficiently produces a fixed 5 V (default) or 6 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.)
