Hi there! Building the Duck module at the moment and noticed some pads on the back side of the control board, under in the jack section labelled for "Response". The BOM says a 3 pin male header goes here however I don't see where else this would connect to. There also 2 vertical pads for F and 2 for S on either side of the response pads which I assume stand for Fast and Slow. Is this possibly for a switch instead of jumpers or is it just a feature that was removed in a previous rev and can be ignored? The jacks cover these pads so if I need them, they all have to be added before I can put in the jacks.
Thanks!
Hey Thrill, Solder a 3-pin header and place a jumper on either the two pins facing F (for fast) or the ones facing S (for slow), depending on your desired setting. For reference, you can view pictures of the back of the module on this website. Click on the image and scroll through them to see the back view. Cheers, Stefan
