This I2C breakout uses its clever Nuvoton microcontroller to help you easily incorporate a digital linear potentiometer into your project. You can directly control the RGB LED inside the pot - meaning it's great for using as an input device which can also show you a colour coded visual status (like a thermostat, or volume control).

Potentiometers have a limited range of motion and are good for dials that benefit from having a set start and end point - if you'd prefer one that can spin round continuously, Pimoroni also makes a RGB Encoder Breakout!

You can attach it to your Pi's GPIO directly or via a breadboard with the included headers, but it's also compatible with Pimoroni's fancy solderless Breakout Garden, which makes it easy to use several different breakouts at the same time.

Features

Nuvoton MS51 microcontroller with built-in 12-bit Analog to Digital Converter (datasheet / Technical Reference Manual)
Rotary encoder (datasheet / drawing)
RGB LED (controllable by PWM)
I2C interface, with a default address of 0x0E
3V to 5V compatible
Reverse polarity protection
Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
Compatible with all models of Raspberry Pi.
Python library

Kit includes

RGB Encoder Breakout (pre-assembled)
1x5 straight male header
1x5 right angle female header
Pimoroni has designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

Software

RGB Encoder Breakout uses the same Python library as the IO Expander Breakout - this example shows you how to read the encoder and control the lights.

Notes

The default I2C address is 0x18, but it's possible to change this in software if you'd like to use multiple IO Expanders, or avoid conflicts with other I2C devices. The new address will be saved in flash memory, so will persist if unpowered.
This board uses a Nuvoton MCU with our custom firmware but if you're brave and hackerly, you can substitute your own firmware to change the way this board works and have a super cheap and capable microcontroller (though this is not for the faint of heart!)
Dimensions: approx 26x24.5x12mm (LxWxH)
