DROK Mini Boost Voltage Converter DC 3.2-13V to DC ±15V Positive Negative Dual Output Power Regulator Module 100mA Step Up Volts Transformer Board

hello youtube today we're going to demonstrate a d-roc DC about adjustable buck it's not a transformer but its circuitry designed to convert 8 to 20 to 8 to 22 volts DC to 1 to 15 volts DC and the schematic here shows that these these are the input leads the red and the black and these are the output leads the black and the yellow and then so the way that you adjust the voltage is there's this little pot on the bottom here and so you can adjust the voltage there now I haven't tried this yet so we're going to hook this up to the regulated DC power supply and check the output voltage and then the specific say it's good up to 3 amps here and I have this DC motor which draws two amps at 15 volts and then we're going to see how this will adjust the speed of the motor which is also the voltage in the amperage so I will get set up and I will be right there so I'll just show you the this is the
