XL4015 5A DC Step Down Adjustable Power Supply Buck Module LED with Voltmeter

The onboard volts display makes it easy to adjust the output voltage to any value between 1.25V -35V. The power supply you use will determine the higher voltage value e.g. a 24V power supply will give you a max voltage for your module of around 23.5V. Although this module can deliver up to 5A it is recommended to use it at 4,5A, you can use it with 5A for short periods.
