Source note
Compiled from the official English specification "LED Display Asynchronous Control System HD-C08L" V1.1 (Sep. 13th, 2025). The card drives modules only through its 8 onboard HUB75E interfaces: the interface description lists no output network port, so the number of Ethernet outputs is recorded as 0. The document lists video container formats, not codecs, and does not mention any video input. 4G, RS-232/RS-485 and voice broadcasting are options; GPS needs a GPS module on the dedicated interface. The document does not name a product series and gives no height for the board.
