The desired module has the ability to increase and decrease the input voltage in an integrated and simultaneous manner. The input voltage range is 4 to 35 volts and the output voltage range is 1.25 to 25 volts. For example, by connecting 12 volts to the input, it is possible to have a lower and higher output at the same time, so that by adjusting the corresponding potentiometer, the input voltage of 12 volts can be converted to 1.25 to 25 volts. Among the uses of this module can be mentioned for solar panels. So that the power of the solar panel in sunny and rainy days, when the voltage is constantly changing, had a constant output by connecting to this module. One of the noteworthy points is that this module can be used to charge the battery due to the ability to adjust the current and limit it, and it has a charge status indicator light. The maximum output power is 15 watts without using a heatsink and can be upgraded to 25 watts using it. Please avoid short circuit and adjust the current using a multimeter and connect the module to it.
