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!\u003c\/p\u003e\n\u003cp\u003eThe 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!\u003c\/p\u003e\n\u003cp\u003eThe 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!\u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32 bit processor with 256KB Flash and 32 KB RAM\u003c\/li\u003e\n\u003cli\u003eNative 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.\u003c\/li\u003e\n\u003cli\u003eCan be used with Arduino IDE or CircuitPython\u003c\/li\u003e\n\u003cli\u003eFour RGB NeoPixel LEDs\u003c\/li\u003e\n\u003cli\u003eTwo Capacitive Touch pads\u003c\/li\u003e\n\u003cli\u003eReset switch for starting your project code over or entering bootloader mode\u003c\/li\u003e\n\u003cli\u003eSlim and cute, keychain-friendly!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003eProduct Dimensions: 31.7mm x 12.1mm x 3.8mm \/ 1.2\" x 0.5\" x 0.1\"\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":39289839910995,"sku":"ADA4870","price":11.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/4870-03.jpg?v=1616600513","url":"https:\/\/shop.pimoroni.com\/en-au\/products\/adafruit-neo-trinkey-samd21-usb-key-with-4-neopixels","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
