Novastar A8s

NovaStar A8s — 512×384 Armor receiving card

The A8s is a previous-generation NovaStar receiving card, now withdrawn from the manufacturer's active catalogue.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 most favourable case in the whole A series: its replacement keeps exactly its capacity.

NovaStar A8s — 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 A8s-N — and we tell you plainly how good the substitution is. The A8s-N keeps the 512×384 capacity in PWM 8-bit and the 70 × 45 mm format: the substitution needs no mapping rework. Only two things to check: minimum voltage rises from 3.3 V to 3.8 V, and weight from 17.3 g to 18.7 g.

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 A8s.
• Planned migration — we also quote the move to A8s-N with the engineering time it implies.

• Status — outside NovaStar's active catalogue: confirm availability before committing.
• Replacement — A8s-N. Substitution with no mapping rework; identical capacity and format.
• 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.
