Module selection and wiring
Check the module driver chip before assigning the receiving-card load. Conventional and ShiXin LS chips use the 128 × 512 specification; PWM chips use 256 × 512. Match the module scan mode and ribbon-cable arrangement to the card, then use intelligent setup and screen wiring settings to configure the display.
Frequently asked questions
How many HUB75E ports does the HD-K08 have?
It has 8 onboard HUB75E interfaces and supports 16 groups of parallel RGB data. A separate adapter board is not required for the documented direct connection.
What is the HD-K08 loading capacity?
The listed loading is 128 × 512 for conventional and ShiXin LS chips, or 256 × 512 for PWM chips. Choose the value for the driver chip used by your module.
Can the HD-K08 work with an asynchronous player?
The specification lists asynchronous dual-mode playback boxes and sending cards, as well as synchronous sending cards and two-in-one video processors. Check the exact sending device and module combination.
What power supply does it require?
The specified input is DC 3.8–5.5V, and working power is 3 W. Use the connection diagram in the PDF for the power connectors.
How can I check module wiring and display output?
Use the PDF connection diagram and interface definitions. The card also provides intelligent setup, screen wiring settings and an onboard display test.
