D90-270 receiving card for LED display cabinets
The Sysolution D90-270 receives display data for LED cabinets and supports parameter readback, cable backup and brightness/chroma adjustment. The Ver.1.0 specification covers single-color, dual-color and full-color screens.
Specification differences: the PDF and original listing do not agree on RGB output count or input-voltage range. The values below retain their source labels. Confirm the actual board revision and pinout before purchase or wiring; the conflicting figures should not be treated as interchangeable ratings.

Frequently asked questions
How many RGB output groups does the D90-270 have?
The sources disagree: the Ver.1.0 technical table lists 24 groups, its feature list says 26, and the original listing includes 24 and 28. Confirm the supplied board and output pinout before selecting a hub board or replacement.
What is the correct supply voltage for the D90-270?
The PDF states +3.5 V to +5.5 V, while the original listing states +3.8 V to +6 V. These are conflicting published ranges, not a combined rating. Confirm the label and hardware revision before applying power.
What screen size can one receiving card control?
The specification gives 128 × 128 pixels as typical and 96K pixels as maximum. The usable layout must also match the module scan and driver configuration.
Does this card support cable backup and parameter readback?
Yes. The PDF lists dual network-cable backup, ribbon-cable data detection and receiving-card parameter readback.
Can the D90-270 replace a different D90 model?
A shared D90 name does not confirm electrical or pinout compatibility. Compare the exact model, board revision, JH1/JH2 pin definitions and module configuration; resolve the voltage and RGB-count discrepancies before replacement.
