Continued from the article 'Peltier Controller Evaluation board TECEV104 (I)'.
In order to better understand this Peltier controller evaluation board, let's get more information about the board.
A tuning circuit and an application circuit constitute this Peltier controller evaluation board. This evaluation board can set the output voltage limit, tune the compensation network, set internal operating temperature point, and has an LED for indicating the temperature status of the Peltier controller. This Peltier controller evaluation board comes with numerous connection pads in order to make connections with external components and instruments.
As shown in the figure below, the Peltier controller is located in the center frame of the evaluation board, thus, it is only applicable for DIP type Peltier controller. The voltages of all its pins can be measured directly by probing the vias on the left and right side of the module sockets which are connected directly with pins of the electronic module. Moreover, the figure below shows the top silkscreen layer. There is no bottom silkscreen layer on the board.
