Roendi (Rotary Encoder with Display) features a STM32L433 MCU, 1.28" TFT round display and a Alps Alpine 15Pulses/30Detent encoder. It can be programed either using ST-LINK/V2 or Arduino IDE, and is open source & open hardware. This rotary encoder is suitable for integration into projects as a unique user interface, or can be used as standalone development board. All pins not used by the encoder are broken out to the peripheral of the board.
Roendi is an excellent interface for a variety of uses, including volume control, temperature control, and light control. It is a useful addition to home automation systems, and would make a unique custom HID device.
Roendi is open source. You can find schematics, pinouts, demo software, enclosure CAD files and more on GitHub.
