Plasma 2350 is an all-in-one USB-C powered controller for WS2812/Neopixel and APA102/Dotstar addressable LED strips. Powered by the RP2350A microcontroller, it can draw up to 3A via USB-C – enough juice to drive a substantial string of LEDs without a separate power supply.

Fully assembled with screw terminals for easy LED strip connection, plus a QW/ST connector for plugging in Qwiic or STEMMA QT breakouts. Includes a user button for switching effects, an onboard RGB LED, and is programmable with C/C++ or MicroPython.
