Inhouse product
The power supply module is a very handy tool and it outputs 1.2V~24V adjustable voltage when it is plugged to USB port or micro USB port. With 3W power, it is commonly used in the research and development of technical engineers, such as debugging instruments. In case of power interruption, the module saves the latest setting value before interrupting. It has high voltage stability for that the output value set by precision potentiometer does not change with the input voltage value.
After switching off the 7-segment Display, you can also switch on/off the output by short pressing the button.
