I have been trying to build a Jetson Nano powered Jetbot using the hardware supplied by WaveShare. I assembled the hardware by following the instructions here. But unfortunately, it doesn't power up when I turn it on. I have checked my Jetson Nano separately and it works fine. Even the batteries are charged and shows about 4.2V when checked with a multimeter. Does anyone have any idea about what might be the problem and how can I fix it?
The jetbot board has to be connected to the power adapter for a while to enable the power of the batteries (even when the batteries are fully charged). This step has to be done only once but is an indispensable step to allow the jetson nano to draw power from the batteries. Apparently, it has not been mentioned in the instructions on the WaveShare website.
