NovaStar MRV336 Receiving Card | HUB75 Specifications
$ 15.00
The NovaStar MRV336 receiving card integrates 12 HUB75 connectors. Its linked Rev1.1.1 specification lists 24 RGB data groups, 1/32 scan support and a single-card resolution of 256 × 226 pixels. Review the specification notes below before matching an existing board.
MRV336 receiving card with integrated HUB75 outputs
The NovaStar MRV336 is an M3-series LED receiving card with 12 integrated 16-pin HUB75 outputs. The Rev1.1.1 specification describes a 24-group RGB data card without a separate HUB structure, with support for 1/32 scan mode.
| Parameter | Specification |
|---|---|
| Output connectors | 12 × 16-pin standard HUB75 |
| RGB data output | 24 groups |
| Scan support | 1/32 scan mode |
| Single-card resolution | 256 × 226 pixels |
| Operating voltage | DC 3.3–5.5 V |
| Limit voltage stated in PDF | 3.0–6.0 V; distinct from the operating range |
| Operating current | 0.45–0.55 A; rated 0.5 A |
| Operating temperature | −20 to +70 °C |
| Operating humidity | 10%–90%, non-condensing |
| Network connections | 2 network ports |
| Board thickness | Approximately 1.6 mm |
| Overall thickness | Approximately 18.5 mm |
| Compliance stated in PDF | EU RoHS |
Specification differences to check
The earlier page text listed 16 RGB groups, expandable to 32, and a DC 3.3–5.0 V supply. The attached manufacturer Rev1.1.1 PDF instead specifies 24 RGB groups and DC 3.3–5.5 V operating voltage. These are different source statements, not interchangeable configurations. The table above identifies the PDF values; confirm the exact board revision before selecting wiring or power settings.
The earlier page also stated “EMC Passed,” while the linked PDF feature list states RoHS compliance. Confirm the certification documentation for the actual supplied board if required. The 256 × 226 resolution appears in both sources, without a frame-rate condition.
Monitoring and calibration
Configuration-file readback, temperature monitoring, Ethernet communication-status detection and supply-voltage detection support maintenance. Pixel-by-pixel brightness and chromaticity calibration stores coefficients for individual LEDs. A pre-stored picture can also be configured.
HUB75 wiring reference
The PDF provides the JH1 pin assignment, including RGB signals, line-address signals, DCLK, LAT, OE and ground. Match the ribbon-cable orientation and the LED module pinout to that diagram before connecting the card. Connector count alone is insufficient to confirm a replacement.

Frequently Asked Questions
How many HUB75 ports does the MRV336 have?
The linked Rev1.1.1 specification lists 12 standard 16-pin HUB75 outputs and 24 RGB data groups.
Why does older MRV336 text mention 16 or 32 RGB groups?
That wording appeared in the earlier product description. The attached manufacturer Rev1.1.1 PDF specifies 24 groups. The sources differ, so verify the board revision instead of treating 16, 24 and 32 groups as interchangeable settings.
What supply voltage should I check for the MRV336?
Rev1.1.1 lists DC 3.3–5.5 V as the operating range and 3.0–6.0 V as the limit range. The earlier page text listed DC 3.3–5.0 V. Confirm the actual board revision and power requirements; the limit range should not be treated as the operating range.
What resolution and scan mode are documented?
The PDF states 256 × 226 pixels per card and support for 1/32 scan mode. It does not specify a refresh-rate condition for the resolution value.
Where can I find the MRV336 pinout and calibration information?
The specification PDF linked above includes the JH1 HUB75 pinout and indicator socket definition. It also confirms pixel-by-pixel brightness and chromaticity calibration and configuration-file readback.
