Adafruit Pixel Trinkey USB Key for NeoPixel / DotStar Driving

Blast-off to Pixel Planet with the Adafruit Pixel Trinkey, a compact and versatile microcontroller board that plugs into your computer's USB port and drives numerous NeoPixel (SK6812, WS2812) or DotStar (AP102) LEDs without soldering or complicated wiring. Powered by the ATSAMD21E18 32-bit Cortex M0+ processor running at 48 MHz with 256KB Flash and 32KB RAM, it supports thousands of pixels, enabling bright, colorful, individually-addressable LED projects.

This USB key supports Arduino, CircuitPython, and Windows 11's built-in Dynamic Light Control, offering flexibility for various development environments. NeoPixels and DotStars require precise data patterns generated by this board, simplifying your LED project setup without bulky external components.

Features a screw terminal block for easy connections for 5V power, Data, Clock, and Ground, compatible with 26 to 18 AWG wires. The board includes level shifting and an onboard RGB NeoPixel LED for status indication. Additionally, a JST SH 3-pin connector provides extra hardware connectivity for sensors like infrared remotes, buttons, or potentiometers.

• ATSAMD21E18 32-bit Cortex M0+ - 48 MHz processor with 256KB Flash and 32KB RAM
• Native USB support for Arduino, CircuitPython, MIDI, HID keyboards/mice, and more
• 0.1" / 2.54mm Terminal Blocks for solderless LED connections
• JST SH 3-pin connector for extra hardware
• Reset switch to restart your code or enter bootloader mode
