The one on the right is likely a buck converter similar to this:
although not identical. The one on the left I have no clue about, likely a sensor of some type (due to the 3 wires out.) Perhaps an IR sensor (or perhaps not!) The web site where you found the images may provide more of a clue as to what they are. Images in general aren’t much use. If you have a part number a google search of the form “fritzing part part_number” will turn up any Fritzing parts that are out there.
