XL4005 DC-DC 5-32V Adjustable Step Down 5A Buck Power Supply Module

A 5 amp step-down converter, a meaningful step up in capability from the common 3 amp LM2596 modules. Useful when the load is genuinely demanding: LED arrays, multiple servos, or a 5V rail feeding a Raspberry Pi and peripherals together. Efficient switching regulation keeps heat manageable, though a heatsink and airflow help at sustained high current. 5A rating handles loads that overwhelm 3A modules; Efficient switching keeps heat manageable; Wide 5-32V input range; Adjustable output via multi-turn potentiometer
