Principle of Operation
The breadboard power supply module receives power from either an external DC source or a USB 5V source. When using the barrel connector, the supported input voltage is 6.5V–12V DC. The module regulates the input to provide selectable 3.3V or 5V power to the connected breadboard rails.
The two rail-selection jumpers allow the upper and lower power rails to be configured independently. Each rail can be set to 3.3V, OFF, or 5V, allowing circuits with different supply requirements to be powered from the same breadboard.
The solderless breadboard provides interconnected contact points for assembling circuits without soldering. The included jumper wires are used to connect components, modules, microcontrollers, and breadboard power rails.
