RGB Encoder Wheel Breakout

by Pimoroni

Add a stylish navigational aid to your project with our fully assembled ANO scroll wheel encoder breakout!

This cool mechanical encoder has five buttons (up, down, left, right and centre) and a rotary scroll wheel (with satisfying clicky detents). We've surrounded it with 24 twinkly RGB LEDs and turned it into a handy, pre-assembled I2C breakout so it's convenient to incorporate into your Raspberry Pi or Raspberry Pi Pico projects.

It's compatible with our fancy Breakout Garden system, where using breakouts is easy as popping it into one of the slots and starting to grow your project, create, and code. It also has two Qw/ST connectors so it can be easily plugged into microcontrollers and HATs with Qwiic or STEMMA QT connectors, like Cosmic Unicorn 🦄 or Wireless Plasma Kit 💀.

Features

Includes

  • RGB Encoder Wheel breakout
  • 1x5 pin header
  • 1x5 right-angle socket header

We've designed this breakout board so that you can solder on the piece of right-angle socket 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

There's a easy to use Python library for using this breakout with a Raspberry Pi computer, with examples that use the encoder and LEDs together to make a clock, stopwatch or handy colour picker.

That's not all! You can also use this breakout with Raspberry Pi Pico and our growing selection of RP2040 boards, using C++ or Pirate brand MicroPython.

Notes

  • The default I2C address of the encoder is 0x13, but it's possible to change this in software if you'd like to use multiples, or avoid conflicts with other I2C devices. The new address will be saved in flash memory, so will persist if unpowered.
  • The I2C address of the LEDs can be changed from 0x77 to 0x74 by cutting the trace on the back of the breakout.
  • Fancy a few extra GPIO? We've added pads that can be used to access some spare GPIOs on the Nuvoton / IO Expander. These can be used as inputs and outputs, they're ADC-capable and PWMable and we've also added convenient power and ground pads. Free GPIO, woo!
  • Want to make a snazzy diffuser for the LEDs? Here's a .dxf file for laser cutting!
  • Dimensions: 48x42x10.5mm (LxWxH, approx). The mounting holes are M2.5 and 34mm apart (centre to centre).

After some time from Pimoroni support I found out how inaccurate my old review is. The issues were entirely my doing. The wheel works great, the lights are plenty bright enough for feedback. All the code needed to communicate with it through micropython is contained within the Pimoroni uf2 file. Old review: The product itself is well built and (from what I can tell) works fully. Unfortunately I wasn't aware before purchasing just how tricky things would be to use it in a micropython setting. Even though we intend to use it in a Circuitpython based project, we began with Pimoroni's flavour of micropython. The documentation is not beginner friendly and I didn't realise I would need to learn to build libraries. I ended up deciding it would be quicker to convert it over to a python library for Circuitpython than it will be for my partner and I to figure out everything else to get it working just to eventually port it anyway. So there it sits, waiting. One day it may get used.
