This simple breadboard power supply stick takes a 4–9V input and outputs a regulated 1.8V or 3.3V, selectable via an on-board switch. All headers are at 0.1" pitch for direct insertion into standard breadboards, and the output pins are spaced to power both breadboard power rails simultaneously.

Input power can be supplied through either the DC barrel jack or the two-pin header. An on/off switch provides convenient power control.

Key Features

• Selectable Output – Switch between 1.8V and 3.3V regulated output
