Description

Our I2C Potentiometer Mini Module provides a convenient solution for applications that require digital readings of a user-set potentiometer.  

This Mini Module allows users to ask for the potentiometer position over the I2C bus, converting tactile movements into digital data that can be used for a multitude of interface applications.

Digitally read the on-board potentiometer and use the incoming data for IoT-based light-dimming applications, or fine-tune program settings using a conventional knob.  

This potentiometer can even be used to digitally control the audio volume of your Raspberry Pi by writing software instead of conventional analog audio signal processing.  Integrated ADC121C021 12-Bit analog-to-digital converter allows up to 9 devices to chain to a single I2C bus, capable of reading 4096 positions per potentiometer.  

Applications: 

  • Light Dimming
  • Motor Speed Control
  • Volume and Tone Controls
  • Medical Instruments
  • Test Equipment 
  • Automotive

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All mini modules are 50.8 x 31.75 mm.
