SR-01 5V 2A Peltier Thermoelectric Cooling Module with Heatsink

The SR-01 Peltier cooling module is a compact, all-in-one thermoelectric solution designed for precise thermal management of small electronic components. This unit integrates a ceramic TE element (23x23 mm) paired with a 40x40 mm aluminum heatsink and a quiet fan, delivering effective cooling capacity without requiring complex assembly or additional mounting hardware.

Operating on a 5V DC supply with a minimum current requirement of 2A, this module is suitable for cooling CPU chips, IR detectors, laser diodes, or experimenting with small-scale refrigeration projects. The integrated design simplifies integration into maker projects and electronics prototyping workflows.

Specifications

Note: For optimal performance, use a 5V power supply capable of delivering at least 2A (such as a power bank or dedicated adapter). An underpowered supply will result in poor cooling efficiency or module shutdown.
