Breadboard trim potentiometer

The Adafruit trim potentiometer is built for breadboarding and prototyping work. Its 9.5 mm square body and 0.1 inch pin spacing let it plug straight into standard solderless breadboards or perfboards. A long grippy knob makes manual adjustment easy during circuit development.

Suits hobbyists and engineers tuning analogue

Makers who need a compact variable resistor for sensor calibration, op-amp gain setting or audio level control will find it convenient. Builders requiring multi-turn precision, sealed construction or surface-mount footprints should look at other component types.

Behaviour under sustained adjustment

The carbon track is rated for 270 degrees of rotation and maintains consistent resistance through repeated turns. No thermal derating or mechanical drift data is supplied, so extended high-cycle use should be validated in the target application.

Questions about this item

What spacing does the trim potentiometer need on my breadboard?

The pins are spaced at 0.1" so they fit standard breadboard and perfboard holes.

Will the 270° rotation work with older through-hole prototyping boards I already use?

Yes, the 0.1" pin spacing matches classic perfboard layouts and the 270° turn gives the same adjustment range as traditional trim pots.

How can I confirm the knob is turning through the full 270° after I solder it in?

Turn the grippy knob from end to end; you should feel a smooth 270° sweep with a definite stop at each limit.
