![]() To solve this issue, PCBs were introduced back in the year 1936. But as the circuits became larger and more complex it became extensively hard to build reliable connections using externals wires. After running the tool, a crosshair with a power port is attached to the cursor, indicating that the tool is ready for use.When PCBs were not discovered, engineers connected all components on a circuit using external wires similar to how it is done on a breadboard today. You can easily access it in the Active Bar or select Place > Power Port from the main menus. In Altium Designer, the power ports are placed using the Power Port tool ( ). In other words, when supplied with 5V current to the input, they produce the 3V current needed to power the other components of our drone. The components that we have placed on this schematic sheet are step-down current converters. Each power port is represented as a graphic element with a name that characterizes the power net and is linked to all the schematic sheets. Modern devices can have several different power supply nets (3.3V, 5V, 1.2V, etc.,), as well as several isolated ground layers (separation of analog and digital ground). The components are connected to a specific power supply net and connected to the ground (a net without current) to ensure potential differences, therefore, you need to define all power connections in your schematic. Almost every device is powered from the outside, whether it's a battery, a power cable or some other type of power device. ![]()
