So basically, I just recieved my LTC3108 breakout board and wanted to test it. The way it (supposedly) works is you solder two specific points on the board together to indicate a specific output voltage. You can see my two joints in the bottom right side of the board, which gives an output of 2.35v at Vout. If you look at my white led, it is set in Vout and my peltier is soldered into Vin. When holding down on the peltier, it doesn't light. The multimeter reads absolutely no voltage going into Vout. Does anything look wrong with my set up? Here is a link to where I bought it with info on its usage in the description.
