Product description: Flexible 8x32 matrix - 256 RGB LEDs - WS2812B individually addressed.
The matrix consists of 256 RGB LEDs, each of which can be controlled separately to display a colour from a 24-bit palette. The elements are evenly distributed in eight rows and thirty-two columns. Only one pin of any microcontroller (e.g. Arduino) is needed to operate the module. The system is powered by 5 V, it consumes maximum 60 mA for each diode (at white).
The matrix is made of a flexible material, which enables bending. In our offer there are also matrices with other dimensions available (in the picture a matrix 8 x 32 RGB LED). The product cooperates with NeoPixel libraries for Arduino.
The applied communication protocol enables serial connection of the dies. Another NeoMatrix should be connected to the output connector, connecting 5 V, GND and DOUT with DIN respectively. The manufacturer points out that when using four or more matrices, the Arduino Uno RAM may not be sufficient. It should also be noted that each subsequent matrix will require an increase in power supply performance.
The device has a 3-pin connector consisting of the following leads:
- GND - module weight
- 5 V - supply voltage, current consumption of one diode is maximum 60 mA, which at 256 diodes gives about 15 A
- DIN - digital control signal from a microcontroller
