Frequently Asked Questions

Q: Can this DC-DC power supply module both step up and step down voltage?

A: Yes! This is a buck-boost (step-up/step-down) converter. It can increase voltage from a lower input to a higher output, or reduce a higher input to a lower output — all within the supported input range of 3.5V–12V and output range of 1.2V–24V.

Q: Can I power this module from a USB power source?

A: Absolutely. A standard USB 5V output falls within the 3.5V–12V input range, making USB power banks and wall adapters compatible power sources for this module.

Q: What is the maximum power this module can handle?

A: The BS DC-DC Power Supply Module is designed for use within 2W of dissipation power. It is best suited for low-power electronics applications such as powering microcontrollers, sensors, and small circuits.

Q: Is any soldering required to use this module?

A: The module comes in an SMD (Surface Mount Device) package. Depending on your application, you may need to solder connections or mount it onto a PCB. It is intended for use by those comfortable with basic electronics assembly.
