This is a compact DC-DC buck regulator module with a wide input voltage range. It can output either 3.3V or 5V by soldering the appropriate switching resistor. The default output is 5V, with an input voltage range of 6–36V. By soldering, it can be configured for a 3.3V output, with an input voltage range of 5–36V. The module features castellated holes with an immersion gold design, a small size, and highly integrated packaging, making it easy to embed into various product applications using multiple methods.
