This TEC/TEG with a model number SP1848-27145 has a size of 40mm x 40mm x 3.6mm. It uses 4.8V and 669mA to operate and produce heat. There are 2 sides to this module, one is the cooling side, and the other is heating. To identify which side is which, you only have to look for the text imprinted in the module. The printed side is the cooling side, and the blank side is the hot side.

You could also add a heatsink for the dissipation of heat and to protect you from getting burned.

You only need to supply this with 4.8V and the connection is as follows: RED for the positive side and BLACK for the negative side.
