Source note
Compiled from the official English specification "Full Color Asynchronous Control Card HD-D16" V2.1 (October 22th, 2024). The card drives modules only through its 4 onboard HUB75E interfaces: the port list reads "5V Power *1, 10/100M RJ45 *1, USB 2.0 *1, HUB75E *4", so the number of Ethernet outputs is recorded as 0. The capacity is printed twice: "65,000 pixels" in the feature list and "1024*64" in the basic parameters; the lower figure is used. The video decoding statements differ: the media table says "support 720P video hardware decoding" and the hardware parameters say "1080p@60fps Hard Decode Playback"; the catalog records 720P and keeps both rows. The text calls the cloud service "HD technology clouds management platform" and "small gray cloud platform"; the communication diagram labels it XiaoHui Cloud. The 4G module, RS-232/RS-485 and the relay are options. The document does not name a product series and gives no height for the board.
