Pololu 5V, 3.2A Step-Down Voltage Regulator D36V28F5
Brand: Pololu
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between 2.5 A and 4 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors
