All Circuit Boards are Flawed! Recall them NOW!!!
All circuits I purchased from this company are flawed! I ordered 3 packs of 5 units in Sept 2025. The 10 kilohm resistor should be connected between the 5 volt Vcc pad and the output pad of phototransistor. It is not connected to anything! Also, the left end of the capacitor is not connected to anything either! This is the second company that I purchased from on Amazon this year that has this identical flaw! I spent weeks trying to figure out why my circuits built around these units did not work. Nothing was wrong with my circuits. Finally decided to trace the components on these units and found the errors. Photo shows the flawed circuit boards from this company and the correct wiring of circuit boards from another company purchased in January 2025. Somebody recently cranked out a bad run of these boards! And these bad boards are now circulating around many companies at Amazon! Do not buy from this company until they locate and pull all the defective boards! I will try to contact the company. I will keep you posted.

Good But Be Careful
These work fine. But be careful. You can burn them up if you plug in the three pronged eye incorrectly (backwards)
