7Semi DS3502 I2C Digital 10K Potentiometer Breakout
7Semi DS3502 I2C Digital 10K Potentiometer Breakout
The 7Semi DS3502 I2C Digital 10K Potentiometer Breakout is a digitally controlled variable resistor module based on the DS3502 IC. It provides a 10KΩ linear-taper potentiometer that can be adjusted through an I²C interface, allowing precise resistance control via microcontrollers. The module offers 128 wiper positions for fine-tuning and maintains its set value in non-volatile memory, ensuring it retains settings after power-off. Compact and easy to interface, it is ideal for applications requiring adjustable voltage, gain control, or brightness tuning without using mechanical potentiometers.
