If your Simon doesn't work right off the bat, don't fret. There are many ways that your board could have an error on it. Look over these troubleshooting tips to help diagnose the problem. This section also goes over how to use the solder wick that came with your kit. This is like an eraser for soldering mistakes, and it can come in very handy if a mistake is made.


LED(s) not lighting up even though you have a sufficient solder joint? Don't fret, there is an easy way to fix it! The most common cause of a failed LED is incorrect polarity. We have designed a special trick into the Simon PCB's design. You can simply cut the two traces and close two jumpers. This will swap the polarity without having to remove the LED.

Close Up Simon PCB's LED

Using a hobby knife, cut both exposed traces directly over the white dots. To test, try using a multimeter set to measure continuity to probe the trace between the pads and LED pins. This can help determine if the traces have been fully cut.

PCB Hobby Knife

Using a soldering iron, close both jumper pads with some solder. The image below shows an example of one of the pads being closed.

Solder Jumpers

Did you accidentally solder a jumper between two legs where it should not be included? Don't fret. Here is a simple process using solder wick to remove the excess solder.

Solder jumper

Locate a solder wick.

Solder Wick

Place solder wick on top of solder.

Wick on Solder

Place iron on top of solder wick. Hold for 3-4 seconds.

Iron, Wick, Solder

Once the solder begins to flow into the wick, pull the wick and iron away at the same time.
