NovaStar AT32 Receiving Card: Smart Choice for LED Screen Control

The AT32 is a compact receiving card for cabinet-level LED control. It needs compatible sending hardware, modules and power. For rental display cabinets, confirm the hub-board pinout, driver IC, scan configuration and source bit depth together.

High-density connectors help limit dust and vibration effects. NovaStar lists RoHS and EMC Class B; these do not establish weatherproofing. This guide uses NovaStar AT32 specifications V1.3.2 (20 May 2025).

Calibration, 3D and monitoring depend on the complete system. Save the working configuration before replacement; see our NovaLCT receiving-card firmware guide and confirm firmware compatibility before updating.

• Pixel-Level Brightness and Chroma Calibration: Works with NovaStar’s calibration system to reduce pixel differences.
• Quick Adjustment of Dark or Bright Lines: Corrects visible brightness differences at module or cabinet seams.
• Multi-Batch Adjustment: Adjusts module or cabinet brightness to reduce batch variation.
• 3D Functionality: Requires a controller supporting 3D.
• Individual Gamma Adjustment for RGB: Requires NovaLCT and a supporting controller.
• 90° Image Rotation: Supports 0°, 90°, 180° and 270° orientations.

Display-feature requirements should be checked before commissioning.

• Smart Module Support: Requires dedicated firmware and compatible smart modules for IDs, calibration storage and monitoring.
• Automatic Module Calibration: Reads stored coefficients from a replacement module’s flash memory at power-on.
• Module Flash Management: Stores and reads coefficients and module IDs on flash-equipped modules.
• Temperature and Voltage Monitoring: Reports card readings without external devices.
• Cabinet LCD Compatibility: A compatible LCD module displays card temperature, voltage and run time.

NovaStar maintenance requirements distinguish card functions from optional module hardware.

• Dual Card Backup: Uses two cards on a hub board designed for backup.
• Loop Backup: Uses primary and backup data connections to the controller.
• Dual Program Backup: Keeps firmware copies to help recover from update problems.

Test switchover during commissioning; these features do not cover every power or hardware failure. Backup specifications.

• 8-bit source: 512×384 at 60 Hz.
• 10/12-bit source: 512×192 at 60 Hz.

Both limits require PWM driver ICs. A 512×384 cabinet therefore exceeds one card’s documented 10/12-bit capacity. Capacity and electrical ratings.

• Up to 32 parallel RGB groups or 64 serial data groups, expandable to 128 serial groups.

The diagram shows JH1 and JH2 in parallel mode: JH1 carries RGB groups 15–32 and power; JH2 carries groups 1–14, Ethernet and control signals. Use the searchable pin tables for exact wiring; serial assignments differ.

• Input voltage: DC 3.8–5.5 V.
• Rated current: 0.6 A.
• Rated power: 3.0 W.
• Static protection: 2 kV; use ESD-safe handling.

Current and power vary with configuration and operating conditions.

• Temperature: −20°C to +70°C.
• Humidity: 10–90% RH, non-condensing.

These are operating limits, not an enclosure protection rating.

• Listed size: 70.0 × 45.0 × 8.7 mm.
• Card weight: 16.5 g.

The drawing shows four 3.2 mm mounting holes and ±0.3 mm tolerance. NovaStar’s mounting notes specify up to 9.5 mm total thickness and 8.0 mm mated hub-board spacing. Request a precision drawing before machining.

No fixed AT32 price is verified here. Request a written quote covering quantity, currency, taxes, shipping, stock, lead time and warranty.

Provide the cabinet model, driver IC and hub-board details. Compare the complete replacement cost, including configuration work and spares, rather than assuming every AT32 offer includes the same service.

The NovaStar AT32 Receiving Card combines calibration, monitoring and backup functions in a compact board. Selection depends on module compatibility, bit depth, cabinet fit and operating conditions—not pixel count alone.

For church LED display projects or other installations, confirm the hardware match, retain configuration and calibration backups, and test one cabinet before applying changes across the screen.
