Pololu 3.3V 3.7A Step-Down Voltage Regulator D30V30F3 _MAKE_TOOLS Traditional Arduino products have 3The Pololu D30V3x line of synchronous buck (step down) voltage regulators generates lower output voltages from input voltages as high as 45V. They are switching regulators (also called switched mode power supplies (SMPS) or DC to DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. This particular model (D30V30F3) takes an input of 3. 3V to
