DS3502 Evaluation Board

Adafruit DS3502 Evaluation Board is designed to evaluate the features and functionalities of the DS3502 potentiometer. The DS3502 is a 7-bit, nonvolatile digital potentiometer featuring an output voltage range of up to 15.5V. This potentiometer allows the microcontrollers to adjust the resistance over an I²C bus. The Arduino, CircuitPython board, or Python-powered computer can communicate with the DS3502 potentiometer via the I²C bus and tell it to vary the resistance. This potentiometer is placed on a breakout PCB with the necessary support circuitry and SparkFun Qwiic compatible STEMMA QT connectors. These connectors allow similarly equipped boards to connect to the potentiometer without any need to solder them. The DS3502 potentiometer features a 7-bit wiper value with 128 possible levels of resistance ranging from 0Ω to 10kΩ.
