Colorlight E320 LED receiving card
The Colorlight E320 is a receiving card for modular LED display systems. It receives screen data from compatible sending equipment and distributes it to LED modules. It is a cabinet-level control component, not a television or a standalone media player.
For AV integrators replacing a card or planning a cabinet, the key checks are the driver IC, scan mode, module resolution and wiring. The published maximum load depends on the driver-chip category; a single headline pixel figure does not describe every installation.

Technical reference: E320 receiving card specification PDF, version V2.3.2. The document also lists 120/240 Hz operation and explicitly notes an effect on loading capacity. Confirm the supported load at your required frame rate before ordering.
Match the card to the cabinet

Use the product image to identify the card layout, then compare it with the existing board. Record the module model, driver IC, scan ratio, connector pinout and cable direction. A matching connector shape alone does not establish electrical or configuration compatibility.
For example, a 256 × 512 cabinet contains 131,072 pixels. That arithmetic is useful for planning, but it does not prove that a particular card orientation, scan setting or driver IC will support the layout. Have the complete cabinet configuration checked instead of selecting solely by total pixel count.
When reviewing the complete system, you can browse our LED receiving cards and LED sending cards. Keep the sender, receiver and module configuration in the same project record.
Frequently asked questions
What power and dimensions does the E320 require?
V2.3.2 specifies DC 3.8–5.5 V, 0.6 A and 3 W rated power. Dimensions are 145.2 × 91.7 × 18.4 mm, with a weight of 94 g. Use only one of the two power inputs as instructed in the document.
Does 240 Hz mean the maximum load always applies?
No. The referenced specification states that high-frame-rate operation affects the load. Frame rate and the LED module’s refresh behavior are different parameters. Send both requirements, together with the driver IC and scan mode, for a configuration review.
Can an E320 play a video file by itself?
No. The receiving card is part of the LED control chain. Plan compatible sending equipment and a content source; do not treat the board as a complete playback system. For stored-content projects, review our LED media players with the proposed screen setup.
What should be saved before replacing a receiving card?
Save the working screen configuration and calibration data where available. Photograph the wiring, label the cables and record the current hardware and firmware versions. Have the replacement and configuration file checked before installing it across the screen.
Does loop redundancy remove the need for a wiring plan?
No. The specification includes loop redundancy, but a redundant path must be designed and configured with the sending equipment. Ask for the connection plan and a commissioning test; do not assume that simply adding a second cable establishes a working backup.
Request an E320 compatibility check
Ask EagerLED to check your Colorlight E320 configuration. Provide clear photos of the existing card and connectors, cabinet pixel dimensions, module and driver IC details, scan ratio, sender model, firmware version, required frame rate and quantity.
Include the delivery destination and ask sales to confirm the supplied hardware revision, accessories, availability, freight and delivery estimate for your order. For repairs, keep the original configuration until the replacement has been tested on the actual cabinet.
