Peltier Cooler for 5V Projects

This 30 x 30 mm thermoelectric module creates a temperature differential when powered from a 5 V supply. It contains 127 Peltier elements and is rated for a maximum 65 °C difference at zero heat load. The red and black leads are 140 mm long for easy breadboard or terminal connections.

Makers needing compact spot cooling.

The module draws about 1.5 A at 5 V, so a 5 V 2 A adapter is recommended. It suits hobbyist experiments, small enclosure cooling or sensor temperature control where space is limited. Builders who must dissipate more than a few watts continuously should look at larger TEC devices or active compressor systems.

Silicone seal and wire length aid integration

A factory-applied silicone seal protects the element edges from moisture during thermal cycling. The 140 mm lead length lets you route power away from the hot side without solder extensions. No driver board, thermal paste or heatsink is included, so you must add your own heat-rejection solution to maintain the cold-side temperature.

Questions about this item

What power supply do I need to run this 5 V 1.5 A Peltier module?

Use a 5 V source capable of at least 2 A; the module draws about 1.5 A at 5 V and has a 2.5 Ω DC resistance.

Can I stack this 30 mm cooler on an existing copper heatsink I already own?

Yes, the 30 × 30 mm cold face will mate with any flat heatsink of equal or larger size; apply thermal paste and clamp evenly.

How do I verify the 65 °C temperature differential is being reached after installation?

Measure both ceramic faces with a thermocouple; the delta should approach 65 °C when the hot side is well sunk and the cold side is unloaded.
