LED Matrix 8×8 Addressable LED with 64 x WS2812B, works with Neopixel Library for Arduino
A matrix of 8×8 fully addressable RGB LEDs in the big 5050 SMD package (5×5 mm), compatible with Adafruit’s “Neopixel” Arduino library for WS2812B LEDs.
The module with 64 x WS2812B can be cascaded to build bigger clusters through their data-in and data-out ports.
Every LED contains its own 18mA constant-current driver, and an addressable driver chip, and will work without any current limiting resistors on a power supply of 4-7V.
Since the data protocol is quite timing-specific, you will need a faster microcontroller (at least 8MHz) to control it. You can use it for example with an AVR and Arduino, PIC, STM32 or similar controller. You will have no luck with “interpreted” controllers like Basic Stamp or Picaxe.

Note: These LEDs are called WS2812B and not “Neopixel”. They were invented by Worldsemi and not by Adafruit Industries. Adafruit is one of many manufacturers putting them on PCBs. Please, don’t call them Neopixel.
