Colorlight i5A-905 LED Receiving CardMini Receiving Card — 256×256 Pixels, 16 Groups RGBR’, 16000Hz Refresh
Colorlight i5A-905 LED receiving card built for compact casting aluminum cabinets: 256×256 pixel loading, 16 groups of RGBR’ parallel output, dual auto-identifying RJ45 ports, and up to 16000Hz refresh — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.
What Is the Colorlight i5A-905 LED Receiving Card?
The i5A-905 LED receiving card is Colorlight’s mini-format receiver for the most compact LED display designs — LED color screens and casting aluminum cabinets. It inherits the 5A-series feature set — high refresh, high gray scale, brightness and chromaticity calibration — in a 137×48mm board that powers itself from the pin board.
One card drives 256×256 pixels (columns extendable to 1024 px for special applications) through two 60-pin data outputs, with 16 groups of RGBR’ or 24 groups of RGB parallel output depending on the working mode.
• Loading capacity: 256×256 pixels per card; columns extendable to 1024 px.
• Output: 16 groups RGBR’ / 24 groups RGB; 2× 60-pin data ports (J1/J2).
• Network: dual RJ45 ports with automatic identification (in/out at random).
• Refresh rate: up to 16000Hz (static 64×64); 10000Hz at 1/8 scan.
• Gray scale: 65536 levels; OE minimum unit 8ns.
• Size: 137×48mm, 70g; DC 3.3–6V, 0.6A rated, 3W.

Evidence note: all figures cross-checked against the official Colorlight i5A-905 specification V1.2 (www.colorlight-led.com, 2014/06/18). Working-mode pin definitions differ by interface mode — confirm the mode with the cabinet file before field swaps.
Why the i5A-905 Fits Casting Aluminum Cabinets
Power From the Pin Board
The card draws its supply directly through the pin board — no separate power cable inside the cabinet. In compact casting aluminum designs where every gram and every wire matters, that removes one failure point per card.
Two 60P Outputs, Three Working Modes
J1 and J2 carry 16 groups of RGBR’ in the standard 1/32-scan mode — the output format fine-pitch color screens and casting cabinets are built around. Pin definitions change per working mode, so cabinet files must match the mode.
16000Hz for Camera Capture
Up to 16000Hz refresh at static 64×64 keeps scan lines out of phone and broadcast cameras — the difference between a screen that looks clean on video and one that shows rolling bands on the feed.
i5A-905 Pixel Capacity Calculator: How Many Cards for Your Screen?
Each card loads 256×256 pixels (columns to 1024 px in special applications). Run the division before ordering.
Example 2: a 1024×512 wall = 524,288 px → 8 cards minimum by pixel count — but always verify against cabinet layout, scan mode, RGB data groups and port allocation before fixing the final quantity; the pixel division is the theoretical lower bound only.
Send us your cabinet model and scan mode for a free card-count calculation with your receiving card plan.
When Should You NOT Choose the i5A-905?
• Your card must expose HUB75E module connectors — the i5A-905 drives modules through the 60P ports and the cabinet’s HUB board, not directly.
• You need 32 RGB data groups — consider the Colorlight i6 / i9 receivers instead.
• You run 1/64 scan modules — the i5A-905 supports static to 1/32 scan.
• You need DDR2 SODIMM maintenance swapping — the i6’s socketed design is built for that.
The i5A-905 is a specialist for mini casting cabinets — outside that form factor, the rest of the Colorlight i-series covers the job.

How to Wire the i5A-905 Receiving Card
Two cables and the pin-board power are all the wiring this card needs inside the cabinet.
- Power: the card is powered from the pin board — no external supply wiring.
- Network: RJ45 A/B connect the daisy chain; ports auto-identify direction.
- Module outputs: J1/J2 60P cables to the module HUB boards.
- Optional: external interface for indicator lamp and test button; multifunction card for temperature/humidity/smoke monitoring and remote relay power control.

i5A-905 Setup with LEDVISION — Step by Step
The i5A-905 is configured inside Colorlight’s LEDVISION software as part of the full control system (sender → receiving cards → modules).
- Step 1 — Install LEDVISION from Colorlight’s official site and connect the sender.
- Step 2 — Detect the chain: LEDVISION finds sender and all receiving cards automatically.
- Step 3 — Screen setting: cabinet files, module layout and scan mode (static to 1/32).
- Step 4 — Connection parameters: map the daisy-chain route and port allocation.
- Step 5 — Calibration: load brightness and chromaticity calibration data for pixel-level uniformity.
- Step 6 — Test: send test patterns; verify refresh rate and gray scale before content.
- Step 7 — Save and backup: store the configuration file for field replacement.
