Adafruit NeoKey Trinkey - USB NeoPixel Mechanical Key Switch

The NeoKey Trinkey is a unique circuit board that combines the functionality of a USB key, an Adafruit Trinket, and a mechanical keyboard switch. Powered by a Trinket M0, it features a NeoPixel LED and a Cherry MX-compatible switch. Inspired by single-key macro pads, the NeoKey Trinkey plugs directly into your computer's USB port and is fully programmable. It has an ATSAMD21 microcontroller, a capacitive touch input, and a reset button for bootloader mode. The board is compatible with CircuitPython or Arduino and supports serial, MIDI, or HID over USB. USB NeoPixel Mechanical Key Switch board is perfect for simple projects, such as a macro-controller, password entry tool, or custom keyboard key. Note that the key switch is not included, allowing users to choose their preferred MX-compatible switch. The NeoKey Trinkey is compact, durable, and an affordable option for both beginners and advanced developers. Features: TSAMD21E18 Processor: 32-bit Cortex M0+ at 48 MHz with 256KB Flash and 32KB RAM. Native USB Support: Compatible with all OS, usable as USB serial console, MIDI, HID (Keyboard/Mouse), or a disk drive for Python scripts. Arduino & CircuitPython Compatible: Can be programmed with Arduino IDE or CircuitPython. RGB NeoPixel LED: Single reverse-mount RGB LED for customizable lighting. Capacitive Touch Pad: One touch-sensitive input for interactive projects. Cherry-MX Compatible Footprint: Supports nearly any mechanical switch (center-nub hole, side-nubs must be clipped). Reset Switch: Allows restarting project code or entering bootloader mode. Compact & Keychain-Friendly: Small and portable design for easy carrying.
