The thermoelectric cooler is also known as TEC or Peltier Module creates a temperature differential on each side. One side gets hot and the other side gets cool. They use to either warm something up or cool something down; above all, you can use either side. You can also take advantage of a temperature differential to generate electricity.

Operating Tips:

1. Max. Operating Temperature: 138 Degree C
2. Do not exceed Imax or Vmax when operating a module.
3. Please carry out moisture protection options (sealing) in final application use.
4. Life expectancy: 200,000 hours
5. Failure rate based on longtime testings: 0.2%.

1 x Type-C USB Female to DIP PCB Breakout Board

This HX711 Load Cell Amplifier Module allows you to easily read load cells to measure weight. This Load Cell Amplifier Module uses 24 high-precision A/D converter chips HX711. This module is specially designed for the high-precision electronic scale design, with two analog input channels, and the internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge-type pressure bridge.
