5V | LEDs require a 5V power supply, this 256 LED display requires a minimum of 1000mA. Also to ensure a steady supply of power as the LEDs illuminate on and off, ensure you have a 1000uF capacitor as close to the display connection as possible (make sure you get the polarity correct, and the rated voltage for the capacitor is at least 10V). If you are creating a battery powered system then you’ll need a booster module such as the Adafruit Powerboost 1000C |
GND | Connect to ground |
ENABLE | The display array is powered when Enable is high (3.3V or 5V) so tie this to a GPIO pin for selective control, or wire high otherwise. |
DATA | The WS28212B LEDs only requires a single pin to drive them, this display integrates a logic level shifter, so the Data line can be 3.3V or 5V logic. |
