## Description

The Adafruit Rotary Trinkey is a tiny USB A board built around the ATSAMD21 microcontroller with a footprint for a standard rotary encoder and a built-in NeoPixel LED. Plug it into any USB A port on your computer and program it as a volume knob, scroll wheel, zoom control, or any custom rotary input device. The board supports CircuitPython and Arduino, and over USB it can appear as a serial console, MIDI device, or HID keyboard/mouse — making it incredibly versatile for custom input projects. A capacitive touch pad and reset button round out the feature set. Key Features ATSAMD21E18 Processor – 48 MHz 32-bit Cortex M0+ with 256 KB flash and 32 KB RAM USB A Plug – Plugs directly into any computer's USB A port, no cable needed Standard Rotary Encoder Footprint – Compatible with any PEC11 or PEC12 style 5-pin rotary encoder (not included) NeoPixel LED – Single RGB under-lighting LED for colour feedback Capacitive Touch Pad – One additional touch input Native USB – Serial, MIDI, and HID (keyboard/mouse) support CircuitPython & Arduino – Full support with existing Rotary, NeoPixel, and FreeTouch libraries Note: This board does not come with a rotary encoder soldered in. You'll need to solder your own PEC11/PEC12-compatible encoder (5 solder points). Choose your favourite encoder and knob to customise the feel. Ideal For Custom volume knobs and media controllers Scroll wheels and zoom controls MIDI controllers and music production tools Macro input devices and productivity shortcuts Package Contents 1× Adafruit Rotary Trinkey (ATSAMD21, NeoPixel, capacitive touch)
