Adafruit Peltier Thermoelectric Cooler Module - 5V/A

Key Features: Generate a temperature differential 5V module Rated for 5W max (5V/1A) Maximum temperature differential (Tmax @ Qc = 0): 65°C Keep it cool with a Peltier module. These unique electronic components can generate a temperature differential when powered. That is to say, 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, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). A fan and/or heatsink is ideal.This module is a 5V module, and is rated for 5W max (5V/1A) but when we plugged them in they seemed to draw more like 1.5A so we suggest Adafruit's 5V/2A power adapter for use.Item SpecificsMax current: 1.5A @ 5VSuggested Voltage range: 5V to 7VMaximum temperature differential (Tmax @ Qc = 0): 65°C127 Peltier elementsDC Resistance: 2.5 ohmsSilicone sealSize: 30 x 30 x 5.3mm x 1.2 x 1.2 x 0.2"Wire Length: 140mm / 5.5"Weight: 15.8g / 0.6oz
