KYStar G628 HUB320 LED receiving card
The KYStar G628 converts incoming LED display data into module control signals. It provides eight standard 26-pin HUB320 interfaces, with 32 groups of RGB data, for compatible LED module connections.
Image adjustment and servicing
The G628 supports general-purpose, PWM and dual-latch driver chips. Point-by-point brightness and chromaticity correction, low-gray compensation and low-brightness grayscale display provide adjustment options for the connected modules.
Configuration readback and one-click repair assist card maintenance. Network communication and cable-connection sequence can be checked in real time. Flexible pixel placement supports special-shaped screens, and program write protection is included for upgrade handling.

Frequently asked questions
How many HUB interfaces does the G628 provide?
It provides eight standard 26-pin HUB320 interfaces and outputs 32 groups of RGB data.
Is HUB320 the same connector as HUB75?
The G628 specification defines a 26-pin HUB320 interface. Check the complete pinout against the module or HUB-board design; a similar interface name does not establish compatibility.
What is the G628 maximum pixel capacity?
The linked G628 specification does not provide a maximum pixel-load value. Confirm capacity for the actual driver chip, scan mode and module configuration before ordering.
What correction and maintenance functions are supported?
It supports brightness/chromaticity correction and low-gray compensation, along with configuration readback, one-click repair and real-time network/cable-sequence detection.
