## Description

Allows electronic resistance adjustment directly from Arduino and other development boards, ideal for calibration, level control or prototyping. It operates at 3-5V, offers a 0-10k range via the compatible X9C103S chip, has 33 setting positions for repeatable adjustments, and VL and VH accept signals between -5V and +5V.
Digital potentiometer that uses a cheaper alternative to the X9C103S chip, whose resistance can be controlled directly through development boards such as Arduino.
WARNING! This module supports 33 positions!
