RGB LED Matrix 8×8 with 64 x WS2812B RGB, fully addressable
LED Matrix 8×8 WS2812B RGB, 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 Arduino library for WS2812B LEDs (google for “neopixel” library).
The modules 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.
Adafruit registered the brand name “Neopixel” for these LEDs. But the manufacturer is Worldsemi and not Adafruit. Don’t get fooled and believe this would be developed by Adafruit. Adafruit only created a library for Arduino.
