Waveshare 29035 - DC-DC Buck Mini Module, Compact Size, Configurable 3.3V or 5V buck voltage regulation output - SMD Version - DC5-36-TO-DC3V3-5
The Waveshare 3.3V or 5V DC-DC Buck Converter delivers efficient voltage regulation from a wide input range. It lets you choose either 5V (default) or 3.3V output by resoldering a resistor. It supports up to 4A continuous output (potentially 5A with good cooling), making it useful for projects that need reliable power at moderate current. Ideal for embedded electronics, robotics, or integrating into custom power supplies.
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 a black immersion gold process, small in size, and easy to integrate
