Best suited for

  • Driving a cabinet or module group of up to 256 × 640 pixels with a single card.

Key features (manufacturer)

  • 16 on-board HUB75E ports
  • Maximum loading capacity 327,680 pixels (512×640)
  • Conventional chips: 160×1024 or 256×640; PWM chips: 320×1024, 256×1280 or 512×640
  • Any scanning method from static to 1/128 scan
  • Two interchangeable 1Gbps Ethernet ports
  • Works with dual-mode sending boxes, asynchronous and synchronous sending cards and VP series video processors
  • Gray scale 256~65536
  • Rated voltage DC 4.0V-5.5V, power 5W

Capacity and loading area

The card receives data over the Ethernet chain and drives the module group inside this area. The cabinet/module load cannot exceed this area or the capacity of 163,840 px.This figure is for modules with conventional driver chips; the datasheet states 327,680 px for modules with PWM driver chips.

Source note

maxLoadingPixels = 163,840, the figure printed for conventional chips. The document prints two conventional-chip rectangles of the same size, 160*1024 and 256*640; 256*640 is recorded in loadingWidthPx/loadingHeightPx. The headline "Maximum loading capacity: 327,680 pixels (512*640)" equals the PWM-chip rectangles (320*1024, 256*1280, 512*640), which are kept in specs. The document does not state the number of RGB data groups, so dataGroups is null. Dimensions are read from the dimension drawing, which prints no unit. Not stated in this specification and kept from the earlier excerpt of the official product page (not verified against a document): dataGroups.
