Compact DC–DC USB Input Converter Board with realtime display and adjustable output Key benefits Flexible voltage source: converts a standard 5 V USB supply into an adjustable DC output from 1 V to 24 V, eliminating the need for multiple power supplies for lowpower devices. Precise monitoring: builtin LCD shows the actual output voltage in real time so you can set and verify voltage quickly and safely. Efficient and spacesaving: low power consumption and a compact regulator board make it easy to include in portable projects and tight enclosures. Reliable across conditions: designed to operate over a wide temperature and humidity range for use in workshops, classrooms, and field experiments. Main features Input: DC 5 V (USB) Output: adjustable DC 1–24 V Maximum power: 3 W Realtime LCD display of output voltage Compact regulator module with low power consumption Designed for a wide range of operating temperature and humidity How it solves common problems Replaces multiple fixed supplies by providing one adjustable output that covers a broad voltage range. Avoids guesswork and reduces risk of damaging components by showing the output voltage on the integrated LCD. Fits into small project enclosures or portable test rigs where a full bench supply would be impractical. Compatibility and usage notes Compatible with any 5 V USB power source such as power banks, USB chargers, or computer USB ports. Intended for lowpower applications and prototyping; stay within the 3 W maximum output to avoid overload and overheating. Compact form factor suits embedded installations and temporary bench setups. Practical applications Prototyping microcontroller projects and sensor circuits where you need a variable lowpower supply for testing and tuning. Bench testing lowpower analog circuits or modules that require specific voltages without a bench power supply. Powering small LED modules, lowcurrent RF modules, or instrumentation during development (ensure load does not exceed 3 W). Simple to integrate and use Connect a standard 5 V USB source to the board, set the desired output voltage, and monitor the value on the LCD. The module is intended to provide a straightforward, reliable adjustable supply for DIY electronics, education, and lowpower testing.
