A5s Plus Mini Receiving Card
The NovaStar Armor A5s Plus uses high-density connections to a hub board for compact LED cabinet designs. It supports up to 512 × 384 at 60 Hz with NovaLCT V5.3.1 or later, along with calibration, color management and backup functions.
| Parameter | Specification |
|---|---|
| Maximum resolution | 512 × 384 @ 60 Hz; NovaLCT V5.3.1 or later required |
| Data groups | Up to 32 parallel RGB groups or 64 serial groups; expandable to 128 serial groups |
| Interface | High-density connectors |
| Input voltage | 3.3–5.5 V DC; recommended input 5.0 V |
| Rated current / power consumption | 0.6 A / 3.0 W |
| Dimensions / net weight | 70.0 × 45.0 × 8.0 mm / 16.2 g per card |
| Operating conditions | −20°C to +70°C; 10–90% RH, non-condensing |
| Storage conditions | −25°C to +125°C; 0–95% RH, non-condensing |
| Image rotation | 0°, 90°, 180° or 270° |
Image Quality and Latency Conditions
Color management, 18bit+ and pixel-level brightness and chroma calibration support LED image adjustment. Individual RGB Gamma requires NovaLCT V5.2.0 or later and a sending card that supports the function. A 3D-capable sending card is required for 3D output.
The documented one-frame low-latency mode applies at the receiving-card end and only when the LED modules use driver ICs with built-in RAM. It is not a specification for the latency of the entire video system.
Hub-Board Design and Module Features
In 128-group serial mode, Data65–Data128 are multiplexed into Data1–Data64. Use the pin definitions and reference design in the PDF when implementing an expanded data mode or reserved-pin function.
The specification gives a 5.0 mm distance between the outer surfaces of the card and hub board after the connectors are mated and recommends a 5 mm copper pillar. Use a higher-precision structural drawing for production tooling.
Smart-module functions and LVDS transmission require dedicated firmware. Automatic module calibration and module Flash management require modules with flash memory. RFU8 and RFU10 are multiplexed extension pins, so their smart-module and module-Flash assignments cannot be selected simultaneously.
Backup and Service Functions
A5s Plus supports dual-card backup on a suitable hub board, loop backup, dual configuration storage and dual program backup. NovaLCT V5.2.0 or later supports monitoring the primary and backup cards. Mapping, temperature and voltage monitoring, bit-error detection and configuration readback help locate and diagnose a cabinet.
Frequently Asked Questions
What resolution does A5s Plus support?
Up to 512 × 384 at 60 Hz. The specification requires NovaLCT V5.3.1 or later for this loading capability.
Does A5s Plus support 128 serial data groups?
Yes, as an expanded serial mode. Data65–Data128 are multiplexed into Data1–Data64; the hub-board design must follow the documented pin assignments.
When is the one-frame low-latency mode available?
Only with modules using driver ICs that have built-in RAM. The one-frame figure applies to the receiving-card end, not the complete system.
Do smart-module and LVDS functions need special firmware?
Yes. Both functions are identified as requiring dedicated firmware in the V1.1.5 specification.
What power input is recommended for A5s Plus?
The documented input range is 3.3–5.5 V DC, with a recommended input of 5.0 V. Rated current is 0.6 A and rated power consumption is 3.0 W.
