Adafruit Rotary Trinkey - USB NeoPixel Rotary Encoder

Half USB key, half circuit board, the Rotary Trinkey is a compact marvel. Equipped with a Trinket M0 microcontroller, a vibrant NeoPixel, and a rotary encoder, this device offers a delightful fusion of simplicity and functionality.

The Rotary Trinkey easily plugs into any USB A port, serving as a ready-to-go platform for your creative projects. The ATSAMD21 microcontroller provides robust support for CircuitPython and Arduino, allowing for seamless integration with existing libraries such as Rotary, NeoPixel, and FreeTouch.

Its versatile design means it can be a volume knob, a scroll wheel, or a zoom macro tool. Connectivity options over USB include serial, MIDI, and HID, expanding its potential applications.

Features include a 32-bit Cortex M0+ processor running at 48 MHz, with 256KB Flash and 32KB RAM, ensuring powerful processing capabilities. The single under-lighting RGB NeoPixel LED adds a burst of color, while the capacitive touchpad offers an additional layer of interaction.

The board's standard '5-pin' rotary encoder footprint is compatible with "PEC11" or "PEC12" encoders, making it effortless to customize with your preferred rotary component. Its small, durable design makes it not only portable and affordable but also a perfect candidate for both beginners and seasoned developers looking for a simple yet inspiring project starter.
