The MRV308 is a new receiving card developed by NovaStar. A single MRV308 loads
up to 256x256 pixels.
The MRV308 supports pixel level brightness and chroma calibration, which effectively
removes color difference, greatly improves display consistency of LED images, and
presents finer displays to users.
Software and hardware designs of the MRV308 have fully concerned users'
deployment, operating and maintenance scenarios, enabling easier deployment,
more stable operating and more efficient maintenance.
Integrates 8 standard HUB75 connectors, which makes the HUB board
Adopts the Gigabit Ethernet port, which can connect to the PC.
Supports pixel level brightness and chroma calibration.
Supports setting of images pre-stored in the receiving card.
Supports status detection of temperature, voltage, Ethernet cable
communication and video source signals.
Supports the 5-pin LCD module
