Using Cube:Bit with Raspberry Pi Attaching the Raspberry Pi The Cube:Bit is a 3D array of neo-pixels (SK6812-3535 to be precise). As such it can be accessed like any other strip, ring or matrix of neopixels using WS2812B compaible code. The base for the Cube:Bit (available separately) contains a 40-pin GPIO connector, into which a […]Continue Reading...

The current range consists of 3×3, 4×4 and 5×5 slices together with a base unit that allows power to be added easily (big cubes can use […]Continue Reading...
Basic Building Blocks Basic Building Blocks is a range of soldering kits to make Raspberry Pi add-on boards (aka HATs). The 40-pin GPIO connector is already soldered on all boards (including when you purchase “board only” instead of the complete kit). So you typically only have to add a few components and headers by hand. […]Continue Reading...
