It's half USB Key, half Adafruit Trinket...it's Neo Trinkey, the circuit board with a Trinket M0 heart and four RGB NeoPixels for customizable glow.

Adafruit were inspired by some USB key flashlight boards that would turn any battery pack into an LED torch. So they thought, hey what if we made something like that but with fully programmable color NeoPixels? And this is what they came up with!

The PCB is designed to slip into any USB A port on a computer or laptop. There's an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to the four NeoPixel LEDs. Two other pins are used as capacitive touch inputs on the end - if you look carefully you can see the slotted end has left and right touch pads. A reset button lets you enter bootloader mode if necessary. That's it!

The SAMD21 can run CircuitPython or Arduino very nicely - with existing NeoPixel and FreeTouch libraries for the capacitive touch input. Over the USB connection you can have serial, MIDI or HID connectivity. The Neo Trinkey is perfect for simple projects that can use a few user inputs and colorful outputs. Maybe you'll set it up as a simple status notifier, or stretch-break timer, or a macro keypad, or a random color generator, or, hey you could still make it into an LED flashlight if you wanted!

We think its 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.
