Type-C Buck-Boost Converter Module Adjustable 1.2-24V

A plain buck converter only steps voltage down, and a plain boost converter only steps it up - this module does both from the same USB-C or USB input, automatically buck-converting when the target output is below input voltage and boost-converting when it's above, covering a genuinely wide 1.2V to 24V adjustable output range from one small board. That flexibility matters when a project's actual power needs aren't known in advance or vary between different sub-modules being powered from the same source.

A 97% conversion efficiency keeps heat generation minimal even under sustained load, and the onboard LED digital display shows the actual output voltage in real time - genuinely useful for dialing in an exact voltage via the adjustable potentiometer without needing a separate multimeter connected. A one-button output disable lets the converter be powered but not actively delivering voltage, useful for safely connecting a load before enabling power.

Common uses are bench-style adjustable power supplies built around a simple USB power bank or charger, powering mixed-voltage-requirement projects from one USB source, and general voltage-matching between a fixed USB supply and whatever voltage a specific component actually needs.
