B875 Receiving Card for Fine-Pitch LED Displays
The NovaStar B875 connects the LED control system to display modules through eight HUB75E connectors. A single card supports a maximum load of 512 × 512 pixels and up to 16 groups of parallel RGB data. Check the module pinout and cabinet wiring against the original specification when selecting a replacement.

Calibration, Gamma and 3D Requirements
B875 supports pixel-level brightness and chroma calibration with NovaLCT and a calibration platform; the specification recommends CalCube MiniLED V1.1.0 or later. Color management, 18bit+ and quick calibration-coefficient upload are also documented. Dark or bright lines at module and cabinet joins can be adjusted.
Individual red, green and blue Gamma adjustment requires NovaLCT V5.2.0 or later and a sending card that supports the function. For 3D image output, the sending card must also support 3D. These are system-dependent functions, not capabilities supplied by the receiving card alone.
Maintenance and Backup
Mapping displays the receiving-card number and Ethernet-port information on the cabinet. Temperature and voltage monitoring work without peripherals. Configuration readback, firmware readback, bit-error detection and a configurable pre-stored image support maintenance; firmware readback and bit-error detection require NovaLCT V5.2.0 or later.
Loop backup uses primary and backup connections between the sending and receiving cards. Dual configuration storage and dual program backup provide recovery options. The PDF includes HUB75E pin definitions, grounded mounting-hole details and indicator patterns for wiring and diagnostics.
