Adafruit Peltier Thermo-Electric Cooler Module - 5V 1A

Keep it cool with a Peltier module. These unique electronic components can generate a temperature differential when powered.

Apply 5V to the red (positive) and black (negative) wires, and one side will get cold while the other side gets hot. For best results, wick away the heat with a fan or heatsink to prevent the cold side from warming.

This module operates at 5V and is rated for 5W max (5V/1A). However, it can draw more current, so a 5V/2A power adapter is suggested for optimal performance.
