Colorlight 5A-75E receiving card and specification download
The Colorlight 5A-75E is an LED display receiving card with integrated HUB75 module connections. It sits inside the LED cabinet, receiving data from compatible sending equipment and distributing it to the modules. Select it by cabinet wiring, driver IC and hardware revision, rather than by the model name alone.
Looking for the technical document? Download the 5A-75E Receiving Card Specification, V8.2.2. The parameters below refer to that document. The original product photo shows a V7.1 board marking, so ask sales to confirm which hardware and firmware revision will be supplied.

The highest pixel load is configuration-dependent. The document also describes 120/240 Hz operation and notes that high frame rates affect the load. Have the driver IC, scan mode, cabinet dimensions and frame rate reviewed together.
Inspect the board before replacing a card

Compare the existing board with the front view. Check mounting holes, module connector positions, power terminals and network sockets. Keep a photo of the installed cables before removing them, and label each module connection so the cabinet can be restored accurately.

The rear view helps identify the physical board layout. Photos are a reference, not a confirmation of the revision currently available. Send both sides of your existing card and the module label for a replacement review.
Frequently asked questions
What is the maximum load of the 5A-75E?
The linked V8.2.2 specification lists 128 × 1024 pixels with normal driver chips, 256 × 1024 with PWM chips, and 162 × 1024 with Shixin chips. Driver IC, scan mode and frame rate affect the usable configuration; high frame rates reduce loading capability.
Does HUB75 guarantee compatibility with my LED modules?
No. Check the module pin assignment, scan ratio, driver IC, cable direction and configuration file. Matching connectors alone do not confirm the signal mapping.
Which hardware revision and calibration precision apply?
The linked V8.2.2 document lists 8-bit brightness and chromaticity calibration. The original product photo is identified as a V7.1 board. Confirm the actual supplied hardware and firmware revision before using these reference limits for an order.
Can the network sockets accept HDMI video?
No. The RJ45 connections carry LED control data from compatible sending equipment. The receiving card is not a standalone video player and has no documented HDMI input.
What should I do before replacing a receiving card?
Save working receiver settings and calibration files where available. Compare the board layout and power connections, confirm revision compatibility, and test one cabinet before applying settings across the screen. Keep the original configuration until image mapping, color and backup behavior have been checked.
Get a 5A-75E replacement or project quotation
Request a Colorlight 5A-75E compatibility check. Provide the existing board revision, clear front and rear photos, sender model, module driver IC, scan ratio, cabinet pixel dimensions, required frame rate and quantity.
Ask EagerLED to confirm the supplied revision, accessory list, availability, freight and delivery estimate for your destination. You can also compare our LED receiving cards if the existing cabinet requires a different connection layout.
