DC-DC 12V To 3.3V 5V Buck Step down Power Supply Module For Arduino

This power supply module offers flexible voltage conversion. It accepts a DC input of 6V - 12V, with the input voltage needing to be at least 1V higher than the output voltage. It can output 3.3V (±0.05V error), 5.0V (±0.05V error), and handle a load current of up to 800mA. It also allows 12V input to be directly converted to output. The PCB board measures 4.5cm * 4.5cm and comes with a red power indicator LED. The package includes 1 piece of this module, perfect for Arduino projects.

Using this power supply module is easy. First, connect your power source with a DC voltage between 6V and 12V to the input. Make sure the input voltage is at least 1V higher than the output voltage you need. Then, connect your device to the appropriate output (3.3V, 5V, or 12V). You'll see the red power indicator LED light up, which means the module is working. When using, don't let the load current exceed 800mA, or it might damage the module. To keep it in good condition, store it in a dry and cool place. If it gets dirty, use a soft, dry cloth to clean it.
