Our family of I2C-friendly user interface elements grows by one with this new product that makes it plug-n-play-easy to add a 75mm long slide potentiometer to any microcontroller or microcomputer with an I2C port.
Each breakout is 3" long and 0.8" wide, with a single linear slide pot in the center. Underneath, there are four under-lighting NeoPixels that can display any RGB color. In the middle, a small microcontroller takes I2C commands and converts them to analog reads (of the potentiometer) and NeoPixel control. Goes great with the Stemma QT rotary encoder and 1x4 NeoKey QT breakout.
Thanks to the Stemma QT / Qwiic connectors underneath, you can easily connect using QT cables - no soldering required! There's even four I2C selection jumpers that you can cut to change the address from the default 0x30 to any value up to 0x3F so up to 16 slide pots can all share one chained cable.
To get you going fast, Adafruit spun up a custom-made PCB with the seesaw chip and all supporting circuitry for 3 or 5V power and logic. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the rotary encoder or to chain them with a wide range of other sensors and accessories using a compatible cable. QT Cable is not included, but we have a variety in the shop.
You can use this Arduino library to control and read data with any compatible microcontroller. There is also CircuitPython/Python code for use with computers or single-board Linux boards.
