Colorlight i5A-905 LED Receiving Card
The Colorlight i5A-905 is designed for compact, portable LED displays and die-cast aluminum cabinets. It receives data from a compatible Colorlight sending device and drives the connected LED modules through its cabinet interfaces. Its small format and pin-board power connection help fit tight cabinet layouts.
Key specifications

| Scan modes | Static to 1/32 scan |
| Signal output | Up to 16 groups of RGBR′ or 24 groups of RGB, depending on output mode |
| Power input | DC 3.3–6 V; power can be supplied through the pin board |
| Dimensions | 137 × 48 mm |
| Backup | Dual receiving card backup, loop backup and dual-machine backup are supported with a suitable system configuration |
Display and cabinet features
- Supports conventional, PWM and lighting driver chips, subject to module configuration.
- Supports point-by-point brightness and chromaticity calibration.
- Offers flexible data offset and mapping for shaped, spherical and other creative LED displays.
- Two RJ45 network ports support data input and output, including cabinet cascading.
- Designed to improve low-gray detail and refresh performance; the achieved result depends on the LED modules, driver ICs and configuration.
Compatibility and selection
The manufacturer lists Gigabit NIC and Colorlight S, Z and C series sending devices as compatible options. Before ordering, confirm the cabinet connector, output mode, scan configuration, power connection and sending-system setup against your LED module design. The standard 256 × 256-pixel figure is the per-card full-color control area, not a promise that every module arrangement will run at that size.
Frequently asked questions
What is the i5A-905 used for?
It is a receiving card inside an LED display cabinet. It takes the incoming control data and supplies the mapped signals to the LED modules.
Does the card support receiver backup?
Yes. The Colorlight specification describes a two-card backup arrangement within one cabinet. Confirm the required wiring and configuration for your installation.
Installation checklist
- Identify the LED module driver IC and scan mode, then select the matching receiver output mode.
- Confirm the cabinet pin-board or hub connection and supply voltage before powering the card.
- Set the cabinet pixel mapping and data direction in the Colorlight control software.
- If redundancy is required, plan the second receiving card and sender path according to the system diagram.
- After configuration, inspect low-gray content, color calibration and the built-in test patterns on the actual display.
For a replacement purchase, compare the card marking and cabinet interface with the unit already installed. The i5A-905 has a different interface arrangement from other i5A-series models, so matching only the series name is insufficient. If you need a particular pinout, refer to the specification PDF below before ordering.
Conclusion
Choose the Colorlight i5A-905 when a compact cabinet needs a receiver with flexible scanning, module output options and backup support. Check the exact cabinet interface and system configuration before installation.
