How do I drive a Peltier Cooling Plate with USB power? Answered
I just ordered some of these 20mm x 20mm Peltier Cooling Plates and would like to power them with a USB hub.
Their rated at max of 4 amps and a max 3.8 volts and I know that generally USB is 5V and 500mA.
So I know I need to just reduce the voltage, but I'm not sure how to accomplish this.
I think I could drive them at 3.5V and still be okay, Not sure if I need a voltage regulator or if just resistors would do the trick.
