Colorlight i5A-F dual-mode receiving card
This listing describes a Colorlight LED receiving card for synchronous display and asynchronous playback of stored content. The documented fallback function uses onboard memory when the sending signal is interrupted, for applications such as advertising and event displays.
Model identification: the product title uses i5A-F, while the original description uses 5A-F and the parameter table is labelled RDA5F. No specification PDF is attached to this listing. Confirm the label and hardware revision before ordering a replacement.

Offline playback and configuration
Prepare the stored program and verify the transition from the live sending signal to offline playback in the actual display. Available storage does not establish a fixed recording duration. The module configuration, HUB-board layout and sending equipment must match the card revision.
For a replacement, provide the card label, front and rear photos, cabinet pixel dimensions, driver IC, scan ratio and working configuration. Check the required backup behavior as part of commissioning.

Frequently asked questions
Does the i5A-F support both synchronous and asynchronous display?
The existing listing describes synchronous operation and asynchronous playback of stored content. It states that the card can switch to stored-content playback if the sending signal is interrupted. Configure and test the offline content before relying on this behavior.
How much onboard memory is listed?
The product information states 2 Gbit of onboard memory per card. This is a bit-based capacity, not 2 GB; the listing does not specify a guaranteed playback duration.
What is the listed pixel capacity?
The original table lists 512 × 128 pixels for full-color 1/8-scan operation, and a 256 × 256-pixel correction area. These are separate specifications and should not be treated as an unconditional load for every scan mode.
What power supply and board dimensions are listed?
The existing table gives DC 5 V ±10%, 0.6 A, 3 W and a 143 × 93 mm board. That table is labelled RDA5F, while the title uses i5A-F, so confirm the board identity and revision before applying these values.
Can I replace another Colorlight i5A receiving card with this card?
Do not assume interchangeability from the i5A name. This listing mixes i5A-F, 5A-F and RDA5F identifiers. Check the board label, HUB connections, module driver settings and required offline-playback function against the installed hardware.
