Novastar AT30 LED Wall Receiving Card
512×256@60Hz mid-range receiving card — double the AT20’s pixel capacity with 24 parallel RGB data groups, pixel-level calibration, 3D support, individual RGB gamma, 90° rotation, and EMC Class B compliance. The optimal price-to-performance choice for LED displays between 5–15m².
What Is the Novastar AT30 LED Wall Receiving Card?
The Novastar AT30 LED Wall Receiving Card is a mid-range general-purpose receiving card that doubles the AT20’s pixel capacity — supporting up to 512×256@60Hz with 24 groups of parallel RGB data (expandable to 64 serial, up to 128 via multiplexing). It occupies the sweet spot in NovaStar’s AT series: sufficient capacity for mid-size fixed installations where the AT20’s 256×256 limit would require too many cards, but without the premium pricing of the A5s Plus’s advanced Color Management engine.
The AT30 shares the AT20’s full feature set — pixel-level brightness and chroma calibration via NovaCLB, 3D output with compatible controllers, individual red/green/blue gamma adjustment, 90° image rotation, quick dark/bright line correction at module seams, and dual configuration parameter backup — all on an EMC Class B certified hardware platform. The only difference from the AT20 is the vertical resolution: 512 pixels tall vs 256.
For a 10m² P2.5 indoor LED wall, the AT30 needs approximately 13 cards vs the AT20’s 25 — cutting card count, hub board count, and cabling complexity nearly in half for roughly 25–35% more per-card cost. As a LED screen manufacturer, we recommend the AT30 as the default choice for projects in the 5–15m² range where the AT20 becomes impractical but the A5s Plus is overkill.

Novastar AT30 Key Features: Double the AT20’s Capacity, Same Professional Calibration
The AT30 inherits every feature from the AT20 and adds the one that matters most for mid-size displays: 512-pixel vertical resolution.
512×256 — 2× AT20 Capacity
Double the vertical pixels of the AT20. For a 10m² P2.5 wall: 13 cards vs 25 — nearly half the card count, half the hub boards, half the cabling. The 25–35% per-card premium typically pays for itself in reduced hardware and labor for displays over 5m².
Pixel-Level Calibration
Brightness and chroma calibration per pixel via NovaCLB. Eliminates module-to-module variance on indoor LED display screens viewed at close distance. Coefficients persist through power cycles.
3D + RGB Gamma + 90° Rotation
3D output with compatible sending card. Individual red/green/blue gamma for white balance control at low grayscale. Display rotation in 90° increments. Quick dark/bright line fix at seams — instant, no video source change needed.
EMC Class B + Dual Config Backup
Meets residential/commercial EMC standards — safe near audio equipment in churches and conference rooms. Configuration stored in both application and factory areas for instant restoration. High-density connectors resist dust and vibration.
Novastar AT30 vs AT20 vs AT32 vs AT60: Which AT Series Card Fits Your Project?
The AT30 delivers the best price-to-capacity ratio in the series — double the AT20’s resolution for roughly 25–35% more cost.
| Feature | AT20 | AT30 ⭐ | AT32 | AT60 |
|---|---|---|---|---|
| Max Resolution | 256×256 | 512×256 | 512×256 | 512×384 |
| Parallel RGB Groups | 24 | 24 | 32 | 32 |
| Calibration | Pixel-level | Pixel-level | 12-bit precision | 12-bit precision |
| 3D / Gamma / Rotation | ✅ | ✅ | ✅ | ✅ |
| Dual Card Backup | No | No | No | No |
| Best For | Under 5m², budget | 5–15m², mid-range | 5–15m², 32 groups | 10–20m², high-end |
Verdict: The AT30 is the best value in the AT series. It doubles the AT20’s resolution for a modest price increase, making it the default recommendation for any project over 5m². Step up to AT32 if you need 32 data groups; go to A5s Plus if you need Color Management or dual card backup.
Novastar AT30 — How Much Screen Can 512×256 Pixels Actually Drive?
The 512×256 resolution makes the AT30 ideal for mid-size displays. Here is the practical area calculation — and the AT20 comparison that shows exactly when the AT30 upgrade pays for itself.
| Pixel Pitch | Area per AT30 | AT30 Cards for 10m² | AT20 Cards for 10m² | Card Savings |
|---|---|---|---|---|
| P2.5 (Indoor) | 1.28 × 0.64m = 0.82 m² | 13 | 25 | −48% |
| P3.91 (Outdoor) | 2.00 × 1.00m = 2.00 m² | 5 | 10 | −50% |
| P4.81 (Outdoor) | 2.46 × 1.23m = 3.03 m² | 4 | 7 | −43% |
| P10 (Billboard) | 5.12 × 2.56m = 13.1 m² | 1 | 2 | −50% |
Across all pixel pitches, the AT30 reduces card count by 43–50% vs the AT20 — fewer hub boards, fewer power supplies, fewer Ethernet cables, fewer failure points. For outdoor LED screens at P10, a single AT30 drives over 13m².

Novastar AT30 Application Scenarios: Where the Mid-Range AT Series Card Excels
Mid-Size Church & Auditorium Displays
For a 6–10m² P2.5 church stage screen, 8–13 AT30 cards provide full coverage with roughly half the BOM complexity of AT20 equivalents. EMC Class B protects wireless microphones. Pixel-level calibration ensures uniform worship lyrics.
Corporate Lobby & Conference Room Walls
Fine-pitch indoor LED display screens in the 5–12m² range are the AT30’s sweet spot. 512-pixel height handles 16:9 aspect ratios naturally. Pixel-level calibration is essential at P1.8–P2.5 viewing distances.
Retail Digital Signage Networks
For chain stores deploying standardized 3–6m² P3.91 window displays, the AT30’s 512×256 resolution maps cleanly to landscape formats. Consistent card choice across sites simplifies spares inventory and technician training.
P10 Outdoor Billboards
A single AT30 drives 13.1m² of P10 display. For a 40m² highway billboard, only 4 cards needed. The cost savings vs AT20 compound at scale — fewer cards, fewer hub boards, simplified LED screen maintenance.

Technical Deep-Dive
AT30 vs AT20: When Double the Resolution Pays Off — A Novastar AT Series Cost-Benefit Analysis
Published: August 2026 | 7 min read | UnifyLED Engineering Team
The AT20 and AT30 are identical in every specification except one: vertical pixel resolution. AT20 = 256×256. AT30 = 512×256. That single difference triggers a cascade of cost effects — card count, hub board count, power supply count, cabling complexity — that determines whether the AT30’s 25–35% price premium is a bargain or a waste. This article calculates the crossover point: the display area at which the AT30’s reduced card count pays for the premium, and when stepping up further to the A5s Plus makes engineering sense.
The Crossover Point: When AT30 Becomes Cheaper Than AT20
At P2.5 pixel pitch: AT20 covers 0.41m² per card; AT30 covers 0.82m² per card. For a 5m² display: AT20 needs 13 cards; AT30 needs 7 cards. Assuming AT20 = $40/card, AT30 = $52/card (30% premium): AT20 total = $520; AT30 total = $364 — AT30 is 30% cheaper in total card cost at just 5m². Adding hub boards (~$15 each, one per 4 cards): AT20 needs 4 hub boards ($60); AT30 needs 2 ($30). Total: AT20 = $580, AT30 = $394 — AT30 saves $186 (32%). The crossover happens at approximately 3m² at P2.5 — meaning for the vast majority of real-world LED displays, the AT30 is the more economical choice despite its higher per-unit price. For detailed pixel calculations, see our LED pixel pitch guide.
When the AT20 Still Makes Sense
The AT20 remains the better choice for: (1) very small displays under 3m² where the card count difference is 1–2 cards, (2) P10 or larger pixel pitch where a single AT20 already covers 6.5m², and (3) projects where card-level redundancy is not a concern and the absolute lowest per-unit cost is the priority. For everything else — which describes the majority of fixed LED installations in churches, retail, and corporate settings — the AT30 is the mathematically superior choice.
