Novastar MRV412

NovaStar MRV412 — 12-port HUB75E receiving card

The MRV412 is a previous-generation NovaStar receiving card, now withdrawn from the manufacturer's active catalogue. We list it for one precise reason: the installed base. This is the simplest case in the whole range: its replacement is a near drop-in.

NovaStar MRV412 — why this reference is still stocked

On an LED wall, a receiving card is not swapped like a light bulb. Its load capacity determines how the wall is divided into zones, and that division is frozen in the cabinet configuration file. Changing reference means rebuilding that file, revalidating the mapping, and sometimes reworking the internal harness — turning a standard exchange into an engineering job.

Our position: we always state the current replacement card — here the MRV412-N — and we tell you plainly how good the substitution is. The MRV412-N keeps the 12 HUB75E connectors, 24 RGB groups, 512×512 capacity and a near-identical 145.6 × 91.5 × 19.3 mm format. Two caveats only: the supply range rises from 3.3 V to a 3.8 V minimum, and the card adds 0.9 mm of thickness.

On a partially serviced estate, like-for-like replacement is often the cheaper option once engineering time is counted. On a full refurbishment it is the opposite. We quote both.

• Service on a wall in operation — like-for-like replacement without rebuilding the configuration.
• Homogeneous estate — keeping a single card reference across the whole wall.
• Maintenance stock — spare cards on site for critical installations.
• Extending an existing wall — installation already fitted with MRV412.
• Planned migration — we also quote the move to MRV412-N with the engineering time it implies.

• Status — outside NovaStar's active catalogue: confirm availability before committing.
• Replacement — MRV412-N. Near drop-in; check the minimum voltage rising from 3.3 to 3.8 V.
• Supply voltage — DC 3,3 – 5,5 V; recent replacement cards start at 3.8 V, check against older 3.3 V supplies.
• Configuration — any change of reference means rebuilding the cabinet configuration file and revalidating the mapping.
• Clearance — compare dimensions before proposing a substitution: recent cards often add 1 to 2 mm of thickness.
