{"title":"Adafruit Rotary Trinkey - USB NeoPixel Rotary Encoder","handle":"adafruit-rotary-trinkey-usb-neopixel-rotary-encoder","url":"/products/adafruit-rotary-trinkey-usb-neopixel-rotary-encoder","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.\n\nThe 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.\n\nKey Features\n\n\nATSAMD21E18 Processor – 48 MHz 32-bit Cortex M0+ with 256 KB flash and 32 KB RAM\n\nUSB A Plug – Plugs directly into any computer's USB A port, no cable needed\n\nStandard Rotary Encoder Footprint – Compatible with any PEC11 or PEC12 style 5-pin rotary encoder (not included)\n\nNeoPixel LED – Single RGB under-lighting LED for colour feedback\n\nCapacitive Touch Pad – One additional touch input\n\nNative USB – Serial, MIDI, and HID (keyboard/mouse) support\n\nCircuitPython & Arduino – Full support with existing Rotary, NeoPixel, and FreeTouch libraries\n\n\n\nNote: 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.\n\n\nIdeal For\n\nCustom volume knobs and media controllers\nScroll wheels and zoom controls\nMIDI controllers and music production tools\nMacro input devices and productivity shortcuts\n\n\nPackage Contents\n\n1× Adafruit Rotary Trinkey (ATSAMD21, NeoPixel, capacitive touch)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2952,"title":"Default Title","sku":"AF-4964","price":13.55,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
