Flexible USB wiring for broad compatibility - USB plus and minus can be removed separately, enabling integration with a wider range of power sources and wiring configurations. Intuitive and precise current control - The adjustment knob of the constant current potentiometer turns clockwise to increase current and counterclockwise to decrease current, providing simple, repeatable control. Stable current delivery - Delivers a steady current to the load under varying conditions, improving performance for sensitive components. Compact and practical design - Compact form factor designed for easy placement on a workbench or in a compact setup, with straightforward USB wiring options. Practical use scenarios - LED testing and characterization: set and monitor current to evaluate brightness and behavior. - USB-powered prototype development: adjust current to match component limits during iterative builds. - Flexible wiring experiments: remove USB lines to accommodate non-USB power sources or alternate configurations.
