NovaStar receiving cards & firmware that drive the MBI5158
Important: each NovaStar receiving card ships several firmware versions, and each one supports a different group of pixel driver ICs paired with a group of row/scan decode chips — the version label selects the chip group, not a newer/older build. A panel is defined by both its driver IC and its decode/scan chip, so the firmware must list both. To drive the MBI5158, flash the exact version listed for your card below; a higher-numbered version meant for a different chip group will not work.
⚠️ Don't upgrade unless you have a reason to. Receiving-card firmware is not like a controller update that adds features — a higher number just means a different driver-IC group. If your screen works, leave it alone; only re-flash to match a different driver IC.
A card name joined with “/” (e.g. DH7516-S / 7512-S / 7508-S) is a single NovaStar firmware family: those models share one firmware package, so the versions shown for that row are different firmware lines for the same card — not one firmware per model.

Frequently asked questions
What is the MBI5158 LED driver IC?
The MBI5158 is an LED display driver chip made by Macroblock. It is a PWM (constant-current, pulse-width-modulated) driver used on the LED module to control each pixel's grayscale.
Can a NovaStar receiving card drive the MBI5158?
The MBI5158 is not in NovaStar's default driver-IC library, but many NovaStar receiving cards can still drive it depending on the card model and firmware. The reliable way to confirm is to upload your receiving-card config to our free RCFGX viewer, or call us at 321-747-3220.
How do I find out which driver IC my LED panel uses?
Open your receiving card configuration file (.rcfgx) — it records the driver IC type and firmware version. Our free online RCFGX viewer reads this for you without installing NovaLCT.
