Description
The ANO rotary encoder wheel is a unique user interface element reminiscent of the original clicking scroll wheel on the first iPods. This product is a handy breakout board that converts the encoder’s funky pin configuration into a straightforward, breadboard-friendly header strip. This version comes with the encoder pre-soldered for your convenience.
Note that there are no pull-up or pull-down resistors on the PCB. You should use your microcontroller’s button and rotary encoder library or hardware support to interface with the pins.
You will need 7 GPIO pins total: 5 buttons and 2 rotary encoder pins. There are also two common pins, which can be set to ground or VCC, typically ground is used so you can use your microcontroller’s internal pull-ups for buttons and encoders. Wiring is flexible; example code uses GPIO to the commons and sets them as outputs, but direct wiring is possible.
