This breakout PCB converts the ANO rotary navigation encoder's non-standard pinout into a straightforward, breadboard-friendly header strip. The ANO encoder combines a rotary encoder with directional and centre-push buttons — similar to classic scroll wheel interfaces — and this PCB makes it easy to wire up to any microcontroller.
Key Features
- Breadboard-Friendly – Converts the ANO encoder's pinout to standard 0.1" header spacing
- 7 GPIO Required – 5 button pins + 2 rotary encoder pins
- 2 Common Pins – Set to ground or VCC (ground recommended for internal pull-ups)
- Simple PCB – No active components, pull-up or pull-down resistors
Also Available
- ANO Rotary Encoder I2C STEMMA QT Adapter – Seesaw I2C version with STEMMA QT, no GPIO needed
Ideal For
- Custom navigation interfaces
- Menu and settings controls
- Audio volume and media controls
- Breadboard prototyping
Package Contents
- 1× Adafruit ANO Rotary Navigation Encoder Breakout PCB
Important: This is just the breakout PCB — the ANO rotary navigation encoder is not included and must be purchased separately. Soldering is required to attach the encoder to the breakout.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
