Plasma Stick 2040 W (Pico W Aboard)

by Pimoroni

This perky Pico W-powered controller for WS2812/Neopixel/SK6812 LEDs is perfect for coding up some wireless blinkenlight shenanigans.

Plasma Stick 2040 W is a simple RP2040-powered driver board designed to make playing with addressable LED strips easy peasy rainbow squeezy. We've taken a Raspberry Pi Pico W and added a set of screw terminals to make it easy to connect up your LEDs and boost circuitry so they get a nice clean 5V on the power and data lines. We've also added a reset button (because unplugging your USB cable all the time is tedious) and a Qw/ST (Qwiic/STEMMA QT) connector so you can connect it up to breakouts, all without soldering.

We've designed this board with doing cool LED things with wireless in mind, so it doesn't have all the fancy features that you can find on Plasma 2040 - if you'd prefer mod cons like current sensing, buttons, APA102/Dotstar compatibility and USB-C, take a look!

You can program Pico/RP2040 boards in a bunch of different ways, but if you're a beginner we'd recommend using our batteries included MicroPython build for ease of getting started. We've pre-loaded Plasma Stick with pirate-brand MicroPython and some fun examples to help you get started.

Alternatively, you could install CircuitPython on your Pico W! CircuitPython is an easy to use, well-established ecosystem with lots of example code and drivers for interfacing with different kinds of hardware - and it's just got Pico W wireless support, woop!

If you're adapting examples from elsewhere and need to know the pins that Plasma Stick uses, it's GP15 for LED data, GP4 for I2C SDA and GP5 for I2C SCL.

Connecting Breakouts

The Qw/ST connector on Plasma Stick makes it super easy to connect up Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable.

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor. Want to use >2 breakouts at the same time? Try this adaptor!

    About Pico W Aboard

    Our new Pico W Aboard products come with a built in Raspberry Pi Pico W. This means you get all the advantages of a RP2040 microcontroller - a speedy fast dual-core ARM processor, a dynamic, growing ecosystem and a choice of different programming methods to experiment with. Most excitingly though, Pico W has wireless connectivity, so your Pico/RP2040 devices can communicate with each other, and the internet! 🌍
