The Thermoeletric Cooling module comes in a pre-assmebled kit with heat sinks mounted on both sides (smaller one for the cold side and larger one for the hot side). This module is designed to intake a maximum voltage at 12V and draws about 4.5A at this condition. DO NOT use power sources with higher voltage otherwise the unit can get damaged.
The dimensions of this unit are specified below:
This controller module included in the kit allows the TEC module to be controlled electrically (using a 3.3V standard GPIO on the microcontroller) without needing to manually plug-unplug from the power adapter.
To test this, connect a Power Adapter (12V, 7A) at the input side, and the output DC jack connects to the TEC module, as shown in the figure below. Use a 3.3V standard digital signal to control the ON/OFF of the TEC module. If you have PWM signal, you can also adjust the power level by tuning the duty cycle of the PWM signal.
This circuit is implemented on a 2-layer PCB where you can refer the PCB layout as below.
The kit includes an LCD module with breakout pins given in the picture. The driver of the LCD is SH1106 that uses I2C serial communication. The module has also integrated an EC11 incremental rotary encoder.
