## Description

If for any reason you are not completely satisfied, please contact us and we will help you return it and refund it.Highlight:1. On-board voltage, current, and power meter, you can easily use this module without a multimeter, which is simpler and more intuitive;2. Onboard USB interface for easy charging of your digital products; (note: the USB output voltage is consistent with the module output voltage. It is not a fixed 5V output. Please confirm to 5V before charging the USB device, otherwise it may damage your device)3. High power, high efficiency, 5A, low ripple;4. Three major functions:(1) used as a normal step-down module with overcurrent protection capability;(2) it is used as a charger for various voltage value lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), and used in solar panels, wind turbines, etc.;(3) used as a high power LED constant current driving module;5. There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;6. When used as a lithium battery charger, you can set the float voltage and charge current, and the indicator light indicates whether it is charging or is full;7. With current limiting protection;8. The onboard voltage and ammeter can be self-calibrated;9. With heat sink.Application range:1. As a normal buck module with overcurrent protection.Instructions:(1) Press the right button to adjust the digital meter to the [display output voltage] interface, and adjust the "constant piezo transistor" to make the output voltage reach the desired voltage value;(2) Adjust the digital meter to the [display output current] interface, directly short the output end of the module (find a thick wire to short the output end), adjust the "constant current potentiometer" to make the digital meter the current value reaches the preset overcu
