Pololu 3.3V, 2.5A Step-Down Voltage Regulator D24V25F3 ESP32/ESP8275 Number of Digital Inputs 16This small synchronous switching step down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 3. 3 V. The board measures only 0. 7 0. 7, but it allows a typical continuous output current of up to 2. 5 A. Typical efficiencies of 80% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switching
