Receiving Card

The 5A-75B receiving card is a cost-effective product specially launched by Colorlight to better help customers save costs, reduce failure points, and reduce failure rates. On the basis of making full use of the technical advantages of the 5A receiving card, the most common HUB75 adapter board on the market is integrated into the receiving card, which is more reliable, more worry-free, and more affordable under the premise of ensuring high-quality display.


  • Integrated HUB75, no need to equip with adapter board, more convenient and lower cost
  • Reduce the number of plug-in connections, reduce the point of failure, and lower the failure rate
  • Support conventional chips to achieve high refresh, high grayscale, and high brightness
  • Brand new grayscale engine, better performance in low grayscale
  • It can eliminate the details of dark, low gray and reddish, ghosting and other details caused by the design of the unit board
  • Support high-precision integrated point-by-point correction of chroma and brightness
  • Support all conventional chips, PWM chips, Silan chips and lighting chips
  • Support any scan type from static to 64 scans
  • Supports arbitrary extraction points, supports data group offset, and can easily realize various special-shaped screens, spherical screens, and creative displays
  • Support random selection
  • Single card supports 16 groups of RGB signal output
  • Support large loading area
  • Support DC 3.3V~5.5V ultra-wide working voltage
  • Support Colorlight’s full range of sending equipment

With its own test program, it can realize four kinds of monochrome display of red, green, blue and white, scanning display in horizontal sweep, vertical sweep, etc.

Constant red light indicates that the power supply is normal

1 flash/sec:

The receiving card is working normally, and the network cable is connected normally;

10 flashes/sec:

The receiving card is working normally, and the box is in the state of being calibrated;
