Simply send a command over I2C from an Arduino, CircuitPython board, or any Python-powered computer to set the wiper position.\n\nThe 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.\n\nKey Features\n\n\n128-Step Resolution – 7-bit wiper with 0–10 kΩ range for fine-grained resistance control\n\nI2C Interface – Simple digital control from any I2C-capable microcontroller or computer\n\nNon-Volatile Default – Store a power-up wiper position that persists without power\n\n4-Address Support – Configurable I2C address for up to four units on one bus\n\nWide Voltage Range – Analogue voltage input from 4.5 V to 15.5 V\n\nSTEMMA QT / Qwiic – Dual I2C connectors for solderless daisy-chaining\n\n3.3V and 5V Compatible – Works with a wide range of development boards\n\n\nIdeal For\n\nAutomated gain or volume control\nSensor calibration and trimming\nProgrammable voltage dividers\nReplacing mechanical potentiometers in digitally controlled systems\n\n\nPackage Contents\n\n1× Adafruit DS3502 I2C Digital 10K Potentiometer Breakout – STEMMA QT\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5023,"title":"Default Title","sku":"AF-4286","price":10.22,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":18,"option1":"Default Title"}]}
