Rongzhong, thank you for pointing out I put board the board in backward, I changed it back now, but I am somewhat experienced with Arduino and this is not my first project. I need some trouble-shooting from you that is not copy and paste. No servos connected ? Checked. Different USB ports? Checked, Arduino settings? Checked. Powered both with and without external batteries? Checked. For the $600 I spent on two of these kits I would really appreciate some more nuanced help here. There is power, but not communication to the board.
