Recognised & Supported by
Most of the sensors, Development Boards like Arduino, Raspberry Pi and PIC Controllers work on either 5V or 3.3V most commonly available battery we have with us is 9V or 12V lead acid batteries so it is essential that we supply the components with correct voltage otherwise they may misbehave or simply not work at all. Also, fluctuations in power supply will result in errors and garbage data from the sensors. It may also corrupt the SD card on which you are writing the data or cause your program to misbehave. To deal with this problem we can use this Ultra-Small Size DC-DC Buck Converter module which can step down the DC voltages from upto 28V to 5-20V. The output voltage of this module can be adjusted too which means you can control the output voltage of this module. The main advantage of this module is that it can provide a high output current of upto 3A so that you can even connect small motors to it without thinking much but keep an eye on heat dissipation of the module.
Product Description
The module is pretty easy to use. You just have to connect your positive and negative terminals of the battery or DC supply to the input terminals of the module and before connecting it to the components you are supplying power to, check and adjust the voltage of the output terminals by using a voltmeter and the blue potentiometer on the module itself. Keep in mind, it is a buck converter so it cant supply more voltage than the voltage it is provided with.
