NovaStar’s flagship mini LED receiver card — 512×256 loading, 32 parallel RGB groups, EMC Class B and dual card backup in a 70×45 mm, 17.2 g footprint — supplied by Excelled, a trusted LED screen manufacturer for global B2B system integrators.
Quick Answer: What Is the AT30 LED Receiving Card?
The NovaStar AT30 LED receiving card is a high-performance mini receiving card designed for LED display cabinets. It loads up to 512×256 pixels from a 70×45 mm board, uses dust- and vibration-resistant high-density connectors, supports brightness and chroma calibration, smart modules and dual card backup, and works seamlessly with NovaLCT software — suitable for indoor and outdoor LED display applications.
What Is the NovaStar AT30 LED Receiving Card?
The NovaStar AT30 receiver card is the flagship mini-size card in NovaStar’s AT series, loading up to 512×256 pixels from a board that measures just 70.0×45.0×9.0 mm and weighs 17.2 g. It links to the hub board through high-density connectors that resist dust and vibration, and its hardware design meets EMC Class B — a premium electromagnetic compatibility level for a card this small.
Despite its size, the AT30 features the full AT family display toolchain: pixel-level brightness and chroma calibration, dark/bright line adjustment, 3D output, individual RGB Gamma and 90° image rotation. For maintainability it supports smart modules, automatic module calibration, module Flash management, one-click calibration and LVDS transmission that reduces hub-to-module cabling.
Reliability is where the AT series stands apart: dual card backup lets two cards share one hub board so a failed main card hands over instantly, dual power supply detection reports on both supplies, and loop backup, dual program backup and dual configuration parameter backup protect the signal chain — all monitored in NovaLCT V5.2.0 or later.

Why the AT30 Is the Flagship Mini Receiving Card — 512×256 in a 70×45 mm Footprint
Mini receiving cards usually trade loading for size. The AT30 does the opposite: flagship-grade 512×256 pixel loading — twice the AT20 — inside the same 70×45 mm board that weighs just 17.2 g. Three proven design choices make it possible.
AT30 Maximum Resolution — 512×256 Pixels on a 70×45 mm Board
With up to 32 groups of parallel RGB data, or 64 groups of serial data expandable to 128, the AT30 drives dense cabinets that smaller mini cards simply cannot. Reserved pins on the high-density connectors allow custom user functions — rare on cards of this size, and one reason integrators treat the AT series as the premium mini platform.
AT30 EMC Class B — Built for Dusty, Vibration-Prone Sites
Standard mini cards often misbehave in electromagnetic noise. The AT30’s high-density connectors limit the effects of dust and vibration, and the hardware design achieves EMC Class B — the same certification class used on consumer electronics, unusually demanding for an LED control card. Stage rigs, rental fleets and mobile walls are its home ground.
AT30 Dual Card Backup — Redundancy That Fits Where Full-Size Cards Cannot
Full-size receiving cards typically rely on loop backup alone. The AT30 adds dual card backup: two cards can be mounted on a single hub board, and if the main card fails, the backup card serves the display immediately — with the working status of both cards monitored in NovaLCT V5.2.0 or later. With dual power supply detection alongside, it delivers a redundancy level normally found on much larger boards.
How to Install the AT30 Mini LED Receiver Card — High-Density Connector & Hub Board
The AT30 receiver card mounts directly onto the LED module hub board through its high-density connectors — no ribbon cables, no loose headers. Per the official specifications, the distance between the outer surfaces of the AT30 and the hub board after the connectors fit together is 8.0 mm, so an 8-mm copper pillar is recommended, and the mounting holes are GND-enabled. The card is powered through dual DC input connectors and links to the sending controller over two Gigabit Ethernet ports.
AT30 Installation Checklist
- Power off the cabinet before inserting or removing the receiving card.
- Align the high-density connector with the hub board socket and press evenly until seated — the board-to-board distance is 8.0 mm.
- Mount with 8-mm copper pillars at the GND-enabled mounting holes so the card keeps the specified standoff from the cabinet plate.
- Connect Ethernet in loop topology — main and backup lines form a closed loop between the sending controller, e.g. an MCTRL660 LED display controller, and the receiving card chain; if one line faults, the screen keeps displaying.
- Wire one or both DC power inputs — with two supplies connected, the AT30 detects the working status of both.
- Verify indicator status — green running LED flashing once every 1s = normal operation with video source; red power LED always on = power supply normal.
How to Configure the AT30 LED Receiving Card in NovaLCT — Smart Module & Readback
Everything on the AT30 is configured through NovaLCT V5.2.0 or later, NovaStar’s LED configuration tool for Windows. The same software detects every card on the network, runs Mapping, uploads calibration coefficients, manages module Flash memory, monitors dual card backup and both power supplies, counts bit errors, and reads back firmware and configuration parameters for offline archival. The same workflows apply to our other NovaStar cards, such as the MRV328 LED receiving card, so a mixed fleet stays manageable in one tool. Pair the card chain with our VX1000 all-in-one LED controller when the project needs multiple HDMI/SDI inputs and layer processing.

AT30 LED Receiving Card FAQ — Troubleshooting & Common Questions
Q1 What is an AT30 LED receiving card and what does it do?
Diagnosis: The AT30 is a mini LED receiving card from NovaStar’s AT series, loading up to 512×256 pixels. Solution: It sits between the sending controller and the LED modules, driving the cabinet’s RGB LEDs with pixel-level brightness and chroma calibration, 3D, individual RGB Gamma and smart module management, all configured in NovaLCT V5.2.0 or later.
Q2 What is the AT30 price for wholesale orders?
Diagnosis: NovaStar publishes no fixed retail price; genuine AT30 pricing depends on quantity, packing and region. Solution: Excelled supplies the AT30 on wholesale B2B terms. Request a quotation through our contact page with your quantity and destination, and you will receive volume pricing for the factory-standard 40-cards-per-box packing, with a per-card antistatic bag and anti-collision foam included.
Q3 Where can I find the AT30 manual and firmware?
Diagnosis: The official reference document is the AT30 Receiving Card Specifications V1.0.3; firmware and NovaLCT are distributed through NovaStar’s official channels. Solution: Read the V1.0.3 document for connector pin definitions, dimensions, indicators and environmental limits. Update firmware only through NovaLCT V5.2.0 or later — dual application program backup makes an interrupted update recoverable.
Q4 Can the AT30 drive my LED modules?
Diagnosis: A single AT30 loads up to 512×256 pixels with up to 32 groups of parallel RGB data, or 64 groups of serial data expandable to 128. Solution: Compare your module’s row count and scan rate against these limits, then share them with us — we will verify the exact card count before you order.
Q5 How many AT30 cards does my LED wall need?
Diagnosis: Divide the wall’s pixel width by 512 and its height by 256, rounding up each result. Solution: Example: a 1920×1080 wall needs 4 cards across and 5 down, or 20 cards in total. The practical count also depends on the cabinet’s hub-board connector layout and scan rate — send us those details for a verified calculation.
Q6 How does dual card backup work on the AT30 receiving card?
Diagnosis: Two AT30 cards are mounted on a single hub board; the main card drives the cabinet while the backup card stands by. Solution: If the main card fails, the backup card serves the display immediately so operation is uninterrupted. The working status of both cards is monitored in NovaLCT V5.2.0 or later; the backup connection and identifier signals use the reserved RFU15 and RFU17 pins.
Q7 Why does the AT30 use a high-density connector instead of HUB75E?
Diagnosis: High-density connectors seal the data interface more tightly than standard 16-pin HUB75E headers, limiting the effects of dust and vibration. Solution: The result is higher stability on stage rigs, rental fleets and dusty venues, and one reason the AT30 achieves EMC Class B. Use the recommended 8-mm copper pillars at the 8.0 mm board standoff.
Q8 How do I choose between the AT30 and AT20 LED receiving cards?
Diagnosis: Both are AT series mini cards with the same footprint and EMC Class B; they differ in loading — 512×256 for the AT30, 256×256 for the AT20. Solution: Choose the AT30 when cabinets need more than 256×256 pixels or maximum headroom; choose the AT20 for 256×256 budgets. Both support smart modules, LVDS and dual card backup.
Q9 How do I configure the AT30 LED receiving card in NovaLCT?
Diagnosis: Configuration runs entirely in NovaStar’s NovaLCT software (V5.2.0 or later, Windows). Solution: Connect the sending controller and PC to the same network, detect the card, then run Mapping so cabinets show their card numbers, upload calibration coefficients, manage module Flash, set the pre-stored standby image, and monitor dual card backup and both power supplies — with firmware and configuration readback available for offline backup.
