Colorlight K5+ receiving card for fine-pitch LED cabinets
The Colorlight K5+ is a compact receiving card intended for fine-pitch LED cabinets, including rental and fixed installations. It receives display data through a compatible control system and connects to the cabinet through a HUB board. For a replacement, check the complete board-to-HUB arrangement before selecting the card.
The original front and rear photos below show the K5+ model. Keep the existing mounting layout, HUB-board model and configuration file available when requesting a replacement. A similar card name or connector shape is not sufficient evidence of interchangeability.

Read the K5+ Receiving Card Specification for the referenced configuration. The document lists 120/240 Hz operation and notes that it affects loading capacity. The driver IC, scan mode and frame rate must be checked together; do not assume the highest load applies at every setting.
Check the HUB board and physical installation

Photograph the installed card before removal. Record the cabinet resolution, module arrangement, driver IC and HUB-board identification. Save the working screen settings and calibration files where available, then keep them with the installation record.

The rear view shows the board connectors that need to match the cabinet’s HUB design. Check orientation, pin mapping, mounting clearance and power arrangements with the actual hardware. Test a replacement on one cabinet before applying its configuration across the display.
Frequently asked questions
What is the maximum pixel load of the K5+ receiving card?
The specification lists up to 512 × 384 pixels with PWM driver chips, 512 × 256 with normal driver chips and 512 × 324 with Shixin driver chips. Loading depends on the module setup; 120/240 Hz operation affects capacity.
Does one card provide cabinet temperature and humidity monitoring by itself?
The specification says these monitoring functions require support from the cabinet design. Its monitoring-function table also refers to use with a monitoring module. Include the available sensors, monitoring module and HUB design in the compatibility review; do not assume the bare card supplies every measurement.
What does dual receiving-card hot backup require?
The documented arrangement connects two receiving cards to the HUB board to control one cabinet. A single card does not establish that arrangement. Ask for confirmation of the supported HUB board, wiring and failover configuration before specifying hot backup.
Are two network paths and two power supplies the same backup function?
No. A data-path backup addresses a different failure from a power-supply backup. Identify which failures the project must tolerate, then have the data, receiver and power arrangements checked as a system. Commissioning should include tests of the intended failure scenarios.
Can I reuse a configuration from a different receiving-card model?
Have it reviewed first. Driver settings, module mapping and HUB connections must match the replacement hardware. Browse our LED receiving cards and LED sending cards when documenting the complete control chain.
Request a K5+ cabinet compatibility review
Ask EagerLED to check your Colorlight K5+ configuration. Send front and rear card photos, the HUB-board model, module driver IC, scan ratio, cabinet pixel dimensions, sender model, firmware version, frame rate and quantity.
Specify any smart-module, sensor or backup requirements separately. Ask sales to confirm the supplied hardware revision, accessory list, availability, freight and delivery estimate. Our LED controller accessories category can help you review the supporting components with your project requirements.
