Indicators, Testing and Power
A flashing D1 indicator shows normal card operation. Rapid D2 flashing indicates that a Gigabit connection has been recognized and data is being received. External run and data indicators are also supported. The test button checks display brightness uniformity and module flatness; smart settings configure the screen-unit arrangement.
The V0.1 specification gives different voltage ranges in its parameter table, interface description and rated-voltage table. These are shown separately above. Its precautions recommend a standard 5 V supply for stable operation. Confirm the applicable limits for the supplied hardware before installation.
