DC-DC Buck Mini Module 6-36V to 5V 4A

This DC-DC Buck Module is a compact power module made to step down a wide input range of 5-36V to a stable output of either 3.3V or 5V, with an output current of up to 4A. By default, it provides a 5V output and an input range of 6-36V. For added flexibility, it can be configured to deliver a 3.3V output by simply resoldering a resistor and the input range is 5-36V.

This module is great for powering low-voltage devices from higher-voltage sources, making it useful in a variety of electronic projects. Its simple design allows easy integration, providing consistent power to sensitive components like microcontrollers, sensors, and wireless modules.

There are two options to choose from: Board Only and Board with Header and Terminal. Please choose which version you want before adding it to the cart!

Features

• Supports 5~36V wide voltage input, configurable for 5V or 3.3V output, up to 4A output current
  • 5V output by default, and the input voltage range is 6~36V
  • Can be switched to 3.3V output by resoldering an onboard resistor, and the input voltage range is: 5~36V
• Adopts black immersion gold process, small in size and easy to integrate
