The two 5v lines attached to the RPi via the ribbon cable are not to enough to adequately power the RPi 5, especially if attaching any peripherals, like a camera. Until further revisions are done to the PCB, it is recommeded to power the RPi 5 through a USB C connector. You can cut a USB C cable and identify the V+ and Ground lines using a digital multimeter, then solder those lines to the 5v and Gnd test connection points on the motorboard. You can then plug the USB C connector into the RPi 5 to power it. + + ## 5. Motor Board and Brain Board Mating
