SAMD21 NeoPixel USB Stick – USB “TRINKET”

Trinket Usb

We saw a little USB flashlight that had basic capacitive-touch dimming support, so we though up a version that’s just a SAMD21 and four 3535 NeoPixels with two capacitive touch buttons. Very simple but also a great way to do simple coding projects. There’s two captouch pads – one is on the end, which also has a cutout for a lanyard. There’s also a big flat pad on the back kinda behind the NeoPixels. You could use the two buttons for a simple user interface to change the color patterns. Or use Python to send commands from your computer, maybe an adorable little Pomodoro timer? Or a auto-key scripter? Or a keystroke injector? Or a mouse jiggler? MIDI light organ? All sorts of options thanks to our TinyUSB + CircuitPython support for this lil chip! We might make it a bit shorter with only 2 NeoPixels, or double-sided and much shorter.

What do you think we should call this little board? We’re going with TRINKET USB for now.

Some names…

“Trinket Shiny” or “Trinket Lux” (T.lux for short)
USB NeoTrinket
Neotrinket or neon trinket may be neokey or neonkey!
Blinket USB

    Neat! Looking forward to it.

  2. Call it “Tickle”.
    Responds to touch, jiggles the mouse, tickles the keys, sparkles with color. Plug it into a USB power pack and wave it during concerts and parties that will reopen once we’re safe again. I like the two-sided design.

  3. How about "inTrinket"? Trinket, that goes "IN"(ish) the computer

  5. I like "USB NeoTrinket" or just "NeoTrinket". "Trinket" is a hardware naming term I’ve heard in several places, so it’d be hard to remember that it’s *this* trinket if it was not more specific.
