Power Filter Board - power filtration module for the Raspberry Pi

DC-DC step-down converter module 12V 12A used to convert energy from 15-24V input voltage to stable 12V, providing up to 12A current. Thanks to high conversion efficiency (over 90%) and low ripple (<50mV), it is ideal for powering sensitive devices in applications such as robotics, drones or LED lighting systems. Additionally, built-in overheating and short-circuit protection mechanisms ensure reliable operation even in difficult conditions. DFRobot DFR1208

Step-Down Voltage Regulator D24V25F5. Pololu 2850

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 6 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 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.
