NovaStar receiving cards & firmware that drive the FM6124
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 FM6124, 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.

Frequently asked questions
What is the FM6124 LED driver IC?
The FM6124 is an LED display driver chip made by Fineng. 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 FM6124?
The FM6124 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.
