A grid of 64 beautiful SK6812 (WS2812/NeoPixel) addressable LEDs, perfect for Pixelblaze, arranged in an 8x8 matrix. Combines really nicely with the 8 Channel Output Expander
It comes with a 3 wire connector that can plug right in to the output expander (though the 3 pins are ordered differently, just be sure to solder the wire to match).
Connect and configure 8ch expander (optional)
a. Set 64 pixels in general, AND in the channel config
b. Color order is GRB
Define a 8x8 matrix in the mapper using the preset example
Load any pattern that uses render2D()
I had never really seen the 2D/3D patterns before. The examples: cube fire 3D, plasma 3D, sinpulse 3D, fast pulse 3d, or honeycomb 3D all work on 2D and look really cool. “sound - spectromatix optim” also works if you have the sensor board connected.
I noticed my v1 WS2812 output expander has occasional sparkles (glitches) when Pixelblaze is set to a lower global brightnesses. This might be a problem with my soldering though. The newer APA102/WS2812 output expander is perfectly smooth at lower global brightness.
For $15 and 20 min this was pretty easy to get started with a matrix. That is, after I realized I had the 3-pin connector on backwards
