Accurate and Efficient 4 Pin Optocoupler Testing Solution Offered Here

Connect the optocoupler test board to the USB power cord, and test the optocoupler with the test board probe point. If the indicator light is always on or off, remove the optocoupler from the circuit board and insert it into the optocoupler seat of the breadboard to reconfirm the test results.
