Colorlight i5A-907 receiving card for compact LED cabinets
The Colorlight i5A-907 is a compact LED receiving card for portable displays and die-cast aluminum cabinets. It distributes display data to LED modules and supports pixel-level brightness and chromaticity calibration. Its 137 × 48 mm board suits cabinet layouts where connector clearance and mounting space matter.
The specifications below follow Colorlight’s V7.0 datasheet dated July 22, 2020. Check the supplied board revision and module configuration before replacing an existing card or specifying a new cabinet.
i5A-907 specifications and operating limits
| Parameter | V7.0 specification |
|---|---|
| Conventional full-color control area | 256 × 256 pixels per card |
| Calibration area | 256 × 256 pixels |
| Scan support | Up to 1/64 scan |
| Parallel data output | 16 groups of RGBR′ or up to 24 groups of RGB |
| Input voltage | DC 3.3–5.5 V |
| Rated current / power | 0.6 A / 3 W |
| Board size / weight | 137 × 48 mm / 70 g |
| Operating temperature | −25°C to +75°C |
| Data connectors | Five 26-pin interfaces; J5 duplicates J1 data |
The datasheet permits column extension to 1024 pixels for special applications. This is a configuration-dependent dimension, not a 1024 × 1024 loading claim. Confirm the final loading, scan mode and refresh target together.

Display control, calibration and backup
The card supports conventional, PWM and lighting driver chips. Brightness and chromaticity calibration help match pixels across a display. Data-group offset and pixel mapping support freeform and spherical screen layouts, subject to the module wiring and configuration.
Refresh rate depends on the chip, scan pattern and load. For conventional chips, the datasheet lists up to 16,000 Hz at static 64 × 64 loading and up to 10,000 Hz at 1/8-scan 128 × 128 loading. These test conditions should accompany any refresh-rate comparison.
Loop backup and dual-machine backup are supported when the system is wired and configured for redundancy. Temperature, humidity and smoke monitoring require a compatible multifunction card; they are not standalone sensors built into this receiving card.
Check the carrier board before ordering
The i5A-907 can receive power from its carrier board. Match connector pin definitions, power polarity, voltage, mounting holes and module data arrangement before installation. Back up the original screen configuration before replacing hardware.
For a replacement enquiry, provide clear photos of both sides of the existing card, its revision marking, the carrier board, module driver IC, scan ratio and cabinet pixel resolution. Include the sending-device model and required quantity so the replacement can be checked against the actual system.

Frequently asked questions
How many data-output connectors does the i5A-907 have?
The V7.0 specification lists five 26-pin data interfaces. J5 is a horizontal connector carrying the same data as J1; it does not add an independent data group. Pin definitions vary with the selected operating mode.
Does the i5A-907 support 1/64 scan?
The V7.0 datasheet specifies support up to 1/64 scan. Confirm your board revision, module driver and software settings before applying this limit to an older installation.
Can I use a 6 V power supply?
The cited V7.0 specification lists DC 3.3–5.5 V. Use the voltage specified for the supplied revision and verify the carrier-board power input before connection.
Is it interchangeable with every Colorlight receiving card?
Compatibility with Colorlight sending devices does not guarantee a direct hardware swap. Connector assignments, physical fit, loading and the saved screen configuration must also match. Compare the LED receiving card range when selecting alternatives.
Where can I find the pin definitions and full specifications?
