Something I doubted it would really be a probe on a feather but it really is. The board is loaded with Blink as usual, and the probe has a corresponding indicator. I think the most common programming mistake people make is assigning the wrong contact number. Now you can test it without having to go back and look through the code. Simply press the contact with the probe and if the red indicator does not flash, you are connected to the wrong contact. Works, simple, cheap, convenient. Good combo.
