Reset switch for starting your project code over or entering bootloader mode.

One 35mm slide potentiometer with nubbin.

Can be used with Arduino IDE or CircuitPython.

Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, MIDI, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.

ATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32 bit processor with 256KB Flash and 32 KB RAM.

We think it’s just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board, or inspiration for advanced developers to make something simple and fun. So be kind and careful with your Slider Trinkey! It isnt meant for yanking. Please note this board DOES come with a pre-soldered slide pot (there’s really only one that fits and we happen to stock it) Since we use a PCB with a USB A shape, its possible to accidentally yank the board out if you push the potentiometer all way way out and then keep pushing out. Maybe you’ll set it up as a monitor brightness adjuster, or volume control, or color picker. The Slider Trinkey is perfect for simple projects that can use a few user inputs and colorful output. Over the USB connection, you can have serial, MIDI, or HID connectivity. The SAMD21 can run CircuitPython or Arduino very nicely - with existing NeoPixel and our FreeTouch libraries for the capacitive touch input. A reset button lets you enter bootloader mode if necessary.

The third pin can be used as a capacitive touch input. One pin of the microcontroller connects to the middle of the slide potentiometer as an analog input. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. The PCB is designed to slip into any USB A port on a computer or laptop. The circuit: potentiometer connected to analog pin 1 (Trinket 2). Also prints the results to the serial monitor. It’s half USB Key, half Adafruit Trinket, half mini slide pot … it’s Slider Trinkey, the circuit board with a Trinket M0 heart, NeoPixel glow, and a 35mm long 10KΩ slide potentiometer. / Analog input, analog output, serial output Reads an analog input pin, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) of an output pin.
