BTF-LIGHTING WS2812B Individually Addressable 8X8 64 Pixels LED Matrix Panel Flexible FPCB DC5V

Not working.

Great matrix but it is crazy bright at full power and really does draw alot of power so for most uses make sure you drop brightness right down, at minimal brightness it can run from USB power, any more than minimum you'll need external power from a small external power supply or via molex or Sata power. An arduino atmega328p is more than enough to power any designs and I'm using a nano. To get the best look you'll want a diffuser of sorts in front of the led like frosted acrylic (the video uses a little wrapping tissue paper for the same effect)

This is exactly what I wanted. Not the cheapest, but so much more flexibility in the type of effects I can produce with it! Glad I went OTT with the power supply for the whole system as it needs a lot of grunt at low voltage.

I love these panels. They are super easy to get quick results with see Arduino website. I have previously used 8x8 so this 8x32 will need power handling differently. I have tested already to make sure pixels are working by just plugging into Arduino and running a test program.The 8x32 panel is a bit floppy - so to prevent damage by over/repeated flexing I'll need to mount on plywood or similar.

Comes nicely packaged with wires soldered to the back. It has standard connectors that are common with WS2812B style LED strips, with a spare one for hooking the matrix up to your MCU. It's a great product.I put together a test 'Christmas' decoration with it in an hour or two using an arduino, the fastled library and some 3D designed and printed parts (the printing took many hours but the design was quick).

very bright - connected to smartshow controller with no problems
