## Description

This small 8~32V to 5V 3A dual USB power step-down converter supports all 5V main controllers. Its two USB ports can output 5V/3A at the same time. With up to 85% conversion, the buck module offers excellent heat dissipation and has reverse connection protection and overload protection. When the current of any output port exceeds 3.5A, the module will switch off.

With steady output, this Dual USB Buck Converter is able to work for a long time without voltage shift, which is well applicable to demanding occasions like smart home, small car power, robot project, DIY power source, etc.
