Plasma 2350 is powered and programmable by USB-C and, because USB-C is capable of drawing up to 3A of power, that's enough to power a healthy chunk of LEDs. There's a useful button that you could use to switch between effects, plus a reset button and an onboard RGB LED. We've also popped a QW/ST connector on there, to make it super easy to plug in Qwiic or STEMMA QT breakouts.
You can buy a Plasma 2350 on its own, or in a kit with a USB-C cable and some super-cool LED stars, so you can get started lighting stuff up right away.
