Novastar MRV410 series LED receiving card is a 256 × 226 pixel EMC data receiving card for full-colour LED display modules. One card drives up to 24 groups of RGB data or 64 groups of serial data, and it comes in four models — MRV410-1, MRV410-2, MRV410-3 and MRV410-4 — that share the same board and firmware and differ only in connector orientation. All four models comply with the EU CE-EMC and CE-EMC Class B standards, so the MRV410 series suits LED display projects where electromagnetic compatibility matters.
Novastar MRV410 LED receiving card key features
- RGB data output: 16-group RGBR, 20-group RGB or 24-group RGB from a single card
- Serial data output: up to 64 groups from a single card
- Resolution: supports up to 256 × 226 pixels
- Configuration file read back for fast on-site diagnosis
- Temperature monitoring and power supply voltage detection
- Ethernet cable communication status detection
- High grey-scale and high refresh rate
- Pixel-by-pixel brightness and chromaticity calibration — calibration coefficients are stored for every LED
- VCC PIN on each port — the LED module can supply power to the control system
- EMC compliant: meets the EU CE-EMC and CE-EMC Class B standards
Novastar MRV410-1 vs MRV410-2 vs MRV410-3 vs MRV410-4
All four models are the same receiving card with the same resolution and data output. Only the connector position changes, so choose the version that matches the socket on your LED module.
| Model | Connector layout |
| MRV410-1 | Standard model, male connector on top |
| MRV410-2 | Male connector on bottom |
| MRV410-3 | Female connector on top |
| MRV410-4 | Female connector on bottom |
Novastar keeps the standard MRV410-1 in stock, while the other connector layouts are made to order. If you are not sure which version your cabinet needs, send us a photo of the module socket and we will confirm the right model.

Frequently asked questions about the Novastar MRV410
What is the difference between MRV410-1, MRV410-2, MRV410-3 and MRV410-4?
Only the connector position. MRV410-1 has the male connector on top, MRV410-2 has the male connector on the bottom, MRV410-3 has the female connector on top and MRV410-4 has the female connector on the bottom. Resolution, data output and firmware are identical across all four models.
How many pixels can one Novastar MRV410 card drive?
One card supports a resolution of 256 × 226 and outputs up to 24 groups of RGB data or up to 64 groups of serial data.
Is the Novastar MRV410 an EMC receiving card?
Yes. The MRV410 complies with the EU CE-EMC standard and the CE-EMC Class B standard, and it is also RoHS compliant.
Does the MRV410 support pixel-by-pixel calibration?
Yes. Brightness and chromaticity calibration coefficients are stored for every LED, which helps keep colour and brightness uniform across the whole screen.
How do I choose the right Novastar receiving card?
Match the card to the resolution and scan mode of your LED module. The MRV410 covers 256 × 226 pixels; for larger loads compare the Novastar MRV412-N and the Novastar MRV416-N, or tell us your cabinet specification and we will recommend a model.
