Variable Resistor (Potentiometer)

RM065 trimmer potentiometers and WH148 rotary potentiometers provide flexible options for precise and adjustable resistance in electronics projects. Whether you need compact board-mounted tuning (RM065) or manual analog control (WH148), this set is perfect for Arduino, prototyping, and analog circuit calibration.

The RM065 trimmers are compact, screw-adjustable potentiometers ideal for PCB-level fine tuning, while the WH148 potentiometers offer smooth manual control with a knob shaft, ideal for volume, brightness, and analog signal inputs.
