Source note

maxLoadingPixels = 262,144 (256*1024), the only loading figure the document prints ("maximum loading capacity" in the Overview, "Max Recommend" in the Parameters table). The document does not say whether it applies to conventional or PWM chips and prints no separate conventional-chip figure. The document does not state the number of RGB data groups, so dataGroups is null. The interface definition shows four RGB signal sets (R1~R4, G1~G4, B1~B4) on one HUB320 connector. 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.
