Plug it into any USB port and you instantly have proximity, colour, ambient light, and gesture sensing — plus two NeoPixel LEDs and two capacitive touch pads — all programmable with CircuitPython or Arduino.\n\nOver USB, the Trinkey can act as a serial console, MIDI device, HID keyboard/mouse, or a small disk drive for storing Python scripts. It's ideal for projects that use motion or light sensing as intuitive input — wave your hand to trigger actions, detect object colour, or sense ambient brightness.\n\nKey Features\n\n\nAPDS9960 Sensor – Proximity (up to ~15 cm), RGB colour sensing, ambient light sensing, and basic gesture detection via integrated IR LED and photodiodes\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 USB port; appears as serial, MIDI, HID, or disk drive\n\n2 RGB NeoPixel LEDs – Customisable glow for status feedback or ambiance\n\n2 Capacitive Touch Pads – Left and right touch inputs on the slotted end\n\nReset Button – Enter bootloader mode or restart code\n\nCircuitPython and Arduino Support – Libraries available for APDS9960, NeoPixel, and FreeTouch\n\n\nAPDS9960 Sensing Capabilities\n\n\nProximity – Detects objects up to ~15 cm away using reflected IR light\n\nRGB Colour – Identifies colours of bright, reflective objects\n\nAmbient Light – Measures room brightness\n\nGesture – Basic 4-directional gesture recognition using cardinal photodiodes\n\nConfigurable Interrupt – Fires when proximity or colour thresholds are crossed\n\n\nIdeal For\n\nGesture-controlled computer interfaces\nColour detection and sorting projects\nAmbient light-responsive desktop lighting\nSimple HID input devices triggered by proximity or touch\n\n\nPackage Contents\n\n1× Adafruit Proximity Trinkey (assembled)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3248,"title":"Default Title","sku":"AF-5022","price":20.02,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":33,"option1":"Default Title"}]}
