NovaStar MRV340 receiving card for LED display cabinets
The NovaStar MRV340 is an LED receiving board with configuration readback, cabinet-status monitoring and pixel-level brightness and chromaticity calibration. The original product information lists up to 24 RGB data groups and a single-card resolution of 256 × 226 pixels. Match the card to the cabinet wiring, module driver IC and scan settings before ordering a replacement.
MRV340 parameters
| Item | Listed specification |
|---|---|
| Single-card resolution | 256 × 226 pixels |
| RGBR data output | 16 groups |

| Serial data output | 64 groups |
| Configuration and program maintenance | Configuration file readback and program copy |
| Status monitoring | Temperature, power-supply voltage and Ethernet cable communication status |
| Image calibration | Pixel-by-pixel brightness and chromaticity calibration, with coefficients for each LED |
| Stored image | Pre-stored picture setting supported |
| Compliance stated in the original listing | EU RoHS and CE-EMC |
The data-group entries describe listed output capabilities; do not add them together as simultaneous outputs. The original information does not state voltage limits, dimensions, a numerical refresh rate or the conditions for maximum loading. Request the matching specification for the supplied hardware before installation.
Calibration and replacement planning
Brightness and chromaticity calibration supports adjusting individual LEDs using calibration coefficients. The original feature list also mentions high grayscale and high refresh performance without numerical ratings. Final display performance must be checked with the actual modules and controller configuration.
The original description states compatibility with MRV300 functions. This does not by itself establish a drop-in replacement for every MRV300 cabinet. Check the board connectors, pin assignment, module driver IC, scan mode, sending controller and firmware, and save the working configuration before changing hardware.
MRV340 frequently asked questions
What is the listed MRV340 single-card resolution?
The original product information specifies 256 × 226 pixels. No refresh-rate or driver-IC conditions were provided with that value, so confirm the cabinet layout and matching documentation before relying on it for a project.
Can MRV340 replace an MRV300 receiving card?
The original description lists compatibility with MRV300 functions. A replacement still needs a check of connectors, wiring, module scan settings, controller and firmware; functional compatibility alone is not confirmation of a plug-in replacement.
Does MRV340 support configuration readback and monitoring?
Yes, the original feature list includes configuration file readback, program copy, temperature monitoring, Ethernet communication-status detection and power-supply voltage detection.
Does this receiving board play video on its own?
No. It is a receiving board in an LED display control system, not a standalone media player. Identify the sending controller and cabinet configuration when requesting a replacement.
Where can I obtain the MRV340 specification?
No specification PDF was attached to this listing. Ask EagerLED for a document matching the board revision, along with confirmation of electrical limits, dimensions and loading conditions.
Check an MRV340 replacement
Contact EagerLED with photos of both sides of the card, cabinet pixel dimensions, module driver IC and scan mode, controller model, firmware version and the existing configuration file. Include the required quantity for a quotation.
