Adafruit Slider Trinkey - USB NeoPixel Slide Potentiometer
77 units available with a short lead time.
The Adafruit Slider Trinkey is a tiny USB A board built around the ATSAMD21 microcontroller with a pre-soldered 35 mm slide potentiometer and two NeoPixel LEDs. 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.
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.
