Adafruit DS3502 I2C Digital 10K Potentiometer Breakout - STEMMA QT
We have ✅ 1 available of the AF-4286 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit DS3502 is an I2C-controlled digital potentiometer that lets your microcontroller adjust resistance programmatically — no manual knob-turning required. Simply send a command over I2C from an Arduino, CircuitPython board, or any Python-powered computer to set the wiper position.
The DS3502 provides a 7-bit wiper with 128 discrete resistance levels from 0 to 10 kΩ. You can store a default wiper value that loads automatically on power-up, and configure up to four DS3502 units on the same I2C bus using address jumpers. The analogue voltage on the potentiometer pins can range from 4.5 V to 15.5 V.
Key Features
- 128-Step Resolution – 7-bit wiper with 0–10 kΩ range for fine-grained resistance control
- I2C Interface – Simple digital control from any I2C-capable microcontroller or computer
