The TEC controller evaluation board TEC14MEV1.0 is consisted of a complete tuning and application circuit for driving a TEC. It 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 controller, and has numerous connection pads for making connections with external components and instruments. The TEC control module is located on the lower right of the TEC14MEV1.0 evaluation board. 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. Some of the pins are also connected to the soldering pads with two vias on the edges of the board. The names of all these nodes are marked on the board.
