XL4016 DC-DC Step-Down 1.25-36V 8A Buck Converter + Display

XL4016 DC-DC Step-Down 1.25-36V 8A Buck Converter + Display for Arduino, ESP32, ESP8266, Raspberry Pi

XL4016 step-down converter is a high-performance device for stepping down DC voltage. The module features a clear display and allows smooth adjustment of the output voltage over a wide range from 1.25V to 36V. The device supports current up to 8A. Thanks to a large heatsink, the converter provides effective cooling, which significantly improves its efficiency and operating stability.

Built-in protection guards the circuit against reverse polarity connection, making the module fully safe to use. This protection is implemented with a Schottky diode, which effectively prevents damage to the electronics if power is connected incorrectly.
