Plug it into any USB A port on your computer and program it as a volume control, brightness adjuster, colour picker, or any custom slider 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 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\n35 mm Slide Potentiometer – 10 kΩ analog input, pre-soldered and ready to use\n\n2× NeoPixel LEDs – Reverse-mount RGB LEDs 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 NeoPixel and FreeTouch libraries\n\n\n\nNote: Be gentle when sliding the potentiometer to the extremes — pushing too far outward could pull the board from the USB port. The Slider Trinkey is designed for careful, controlled use.\n\n\nIdeal For\n\nCustom volume and brightness controls\nColour pickers and parameter adjusters\nMIDI faders and music production tools\nMacro input devices and productivity controls\n\n\nPackage Contents\n\n1× Adafruit Slider Trinkey (with pre-soldered slide potentiometer)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2906,"title":"Default Title","sku":"AF-5021","price":20.28,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"Default Title"}]}
