Hey Sir, Here it goes: https://photos.app.goo.gl/QjGkPzCCt5g65B7CA.
Seth P.S. That shows the pair of leads per motor attached to the MotorCape and the 12v battery leads that go from the battery to the MotorCape. Also sir, the power supply for the BBBW is a USB to jack. It turns the board on and powers it well. I have been able to make movement so far w/ motors but they are not acting in accordance to what I have expected. I figured one of the L298 drivers was switched upside down. I cannot be sure of this idea. Anyway, if you cannot view the photo, please reply one day.
