Using the Boost Regulator
Connections
The boost regulator has just three connections: the input voltage, ground, and the output
voltage. These three connections are labeled on the back side of the PCB, and they are
arranged with a 0.1" spacing along the edge of the board for compatibility with standard
solderless breadboards and perfboards and connectors that use a 0.1" grid. You can solder
wires directly to the board or solder in either the 3×1 straight male header strip or the 3×1
right-angle male header strip that is included.
Setting the output voltage
The output voltage can be adjusted using a meter and a light load (e.g. a 1k resistor).
Turning the potentiometer clockwise increases the output voltage. The output voltage can
be affected by a screwdriver touching the potentiometer, so the output measurement
should be done with nothing touching the potentiometer. The potentiometer has no
physical end stops, which means that the wiper can be turned 360 degrees and into an
invalid region in which the output voltage is set to approximately 2.5 V (for both the
2.5 V to 9.5 V and 4 V to 25 V versions). The input voltage should not exceed the output
voltage, so we recommend setting the output voltage with the input voltage set to around
2.5 V.
