Description The NEOPIXEL NEOMATRIX 8×8 is based on 64x WS2812 RGB LEDs with an integrated control circuit hidden underneath each LED. The LED module is ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many modules as you can chain together! Each LED in a module is then addressable as the driver chip is inside the LED. Each LED has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design very slim. Power the whole thing with 5VDC (4-7V works) and you’re ready to rock. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Applications Color Graphic LED display Living room, Interior lighting, Lighting Control Panels, Color LED Lighting for Object Recognition in Robotics Technical Specifications Waterproof: No Basic Colors: Red, Green Blue (24-Bit RGB Resolution) LED Chip Model: SMD5050 Power Source: DC LED type: SMD Model Number: WS2812b chip LED Voltage: 4V-7V DC Max Power Consumption (W): 0.24W x 64 = 15.36W No of LEDs: 8×8 = 64 LEDs in total Expansion: Cascadable / expandable using DIN / DOUT pin Module Dimensions: 65 mm (L), 65 mm (W), 3.2 mm (Height) Pinouts INPUT PORT 5V – This should be a regulated supply voltage between 4V and about 7V. More than that could harm the LED, less than 5V will either reduce brightness, or it just won’t turn on. GND – The common, ground, 0V reference supply voltage. DIN – Data from a microcontroller (or another WS2812 pixel) comes into this pin. OUTPUT PORT 5V – This should be a regulated supply voltage between 4V and about 7V. More than that could harm the LED, less than 5V will either reduce brightness, or it just won’t turn on. GND – The common, ground, 0V reference supply voltage. DOUT – Data is shifted out of this pin, to be connected to the input of another pixel or left floating if it is the last link in the chain. Documents and Downloads Adafruit NeoMatrix Arduino Library.
