Why I'm keeping USART3 for RS485, why I'm starting with blocking, and how to bring up a serial console right inside STM32CubeIDE. Plus running two nodes at once with a ROS2 launch file.

I soldered the battery + switch, checked the shipping voltage of the battery, and attached neodymium magnets for hall sensors to the wheels. Progress got delayed by a week because I had to buy more parts, which is annoying.
