Adafruit Neo Trinkey - SAMD21 USB Key with 4 NeoPixels

The Adafruit Neo Trinkey is a compact USB key featuring a Trinket M0 heart and four RGB NeoPixel LEDs for customizable glow. Designed to fit any USB A port on a computer or laptop, this board is powered by an ATSAMD21E18 32-bit Cortex M0+ processor running at 48 MHz with 256KB Flash and 32KB RAM.

The Neo Trinkey includes two capacitive touch pads for user inputs, and a reset button for bootloader mode or restarting your code. It supports CircuitPython and Arduino, allowing USB serial console, MIDI, keyboard/mouse HID, or even a small disk drive for scripts.

This versatile device can be used as a status notifier, macro keypad, stretch-break timer, random color generator, or LED flashlight. Its slim, durable design makes it an excellent first microcontroller board or a fun project for advanced developers.
