Choosing and configuring the card
Start with the module driver chip and scan mode, then check the required loading and cable layout. The two loading values above apply to different chip types; do not use the PWM value for a conventional-chip module. Intelligent setup and screen wiring settings help match the card to the module wiring. The onboard test function supports checks of display brightness and module flatness.
Frequently asked questions
What is the loading capacity of the HD-K12?
The listed capacity is 192 × 512 for conventional and ShiXin LS driver chips, or 384 × 512 for PWM chips. Check the LED module driver chip before choosing the receiving-card layout.
Does the HD-K12 need a separate HUB adapter board?
The card supports direct module connection through onboard HUB75E interfaces. Its V1.1 PDF contains conflicting interface counts: 12 in the overview and appearance description, and 8 in the parameter table. Confirm the supplied board and cable arrangement before ordering.
Can it work with synchronous and asynchronous LED systems?
Yes. The product specification lists both system types, including sending cards, dual-mode playback boxes and two-in-one video processors. Confirm the exact sending-device and module combination before replacement.
What voltage does the HD-K12 require?
The specified input range is DC 3.8–5.5V, with working power listed as 3 W.
Where can I find the HD-K12 wiring and specification PDF?
