This breakout makes the ANO rotary encoder wheel much easier to use in a breadboard or wired prototype. The encoder is a distinctive navigation control, with a clicky scroll-wheel feel reminiscent of early iPod interfaces.
The board converts the encoder’s unusual pin set into a straightforward header strip, and this version comes with the encoder already soldered in place.
There are no pull-up or pull-down resistors on the PCB, so use your microcontroller’s button and rotary encoder library or hardware support to interface with the pins. You’ll need 7 GPIO total: 5 button inputs and 2 rotary encoder pins.
Two COMmon pins are also provided and can be set to ground or VCC. They are usually tied to ground so you can use your microcontroller’s internal pull-ups; Adafruit’s example code uses GPIO for the COM pins and sets them as outputs for simpler wiring, but they can also be wired directly.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- 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.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
