First off, let me say that this is a great kit platform. For me it has a nice mix of built in features and possible modification. Nothing I could build would be so nicely integrated, and I say that while comparing my Uno based ad-hoc Zumo with your kit.
I recently completed this kit, and started checkout / demos. So far everything seems fine, but I discovered a mistake (mine) and I have a related comment, and question. The mistake was that I soldered the 3 pin jumper headers to the forward sensor array in the wrong 3 hole position. Not sure what the holes I used are for - probably access to the L and R IR sensor circuit. I have fixed my mistake, so if anyone can answer my question, I’m ready to continue the checkout. I stopped before loading the sensor array demo, because I couldn’t figure how to position the jumpers, which was when I found my mistake.
The comment: It would be nice if the assembly section of the manual pointed out more explicitly the correct location for the headers. I know there’s a picture, and I know the exchange rate, and I know it was my fault, still…
The question: I haven’t seen a schematic for this set of boards, so I’m wondering if I’ve damaged anything by installing a jumper across those incorrect pins. I loaded and ran the LCD demo, and the motor test demo, both of which loaded and ran properly.
