Huidu HD-C16L asynchronous LED control and playback card
The Huidu HD-C16L integrates a sending card, receiving card and multimedia playback terminal. Use its 12 onboard HUB75E interfaces for direct module control, or connect compatible HD-R series receiving cards through the Gigabit output for a cascaded display.
The distinction matters for capacity: direct loading is up to 200,000 pixels; cascaded loading is up to 650,000 pixels. These are pixel counts, not power ratings. The reference below follows Huidu’s HD-C16L Specification V1.0, released September 25, 2023. Confirm the board revision, module configuration and required options before ordering.
HD-C16L loading and connection options
| Direct module loading | Up to 200,000 pixels through 12 onboard HUB75E interfaces |
|---|---|
| Cascaded display loading | Up to 650,000 pixels using compatible HD-R series receiving cards |
| PC / input network port | 100 Mbps; parameter configuration, program publishing and LAN/Internet connection |
| Display / output network port | Gigabit Ethernet for cascading receiving cards |
| Wireless control | Standard 2.4 GHz Wi-Fi; AP and STA modes; LedArt mobile-app control |
| USB | Program updates and capacity expansion |
| Audio output | 3.5 mm TRS two-channel output |
Check total pixels and display width together. V1.0 notes reduced capacity when the width exceeds 1920 pixels; confirm the usable load for a wide-format screen before fixing the cabinet layout. A maximum width figure alone does not establish the supported screen area.
Playback, networking and optional functions
The card supports scheduled programs, timed playback, program insertion and multiple content windows. The specification lists simultaneous playback of up to two 1080P video windows, plus common image formats, GIF animation, text, clocks and WPS content. Video-window playback capability is separate from the LED output pixel limit.
Wi-Fi and USB support local content management. Internet-connected management is available through XiaoHui Cloud; the 4G module is optional. UART communication is supported, while RS-232 or RS-485 communication is optional. Confirm the supplied hardware options for the intended installation.
A single onboard relay supports remote power control. Dedicated temperature and GPS interfaces and a general sensor input support external sensing; sensors and GPS modules must match the application. The manual includes the wiring and interface descriptions.
Power, storage and installation reference
| Input supply | DC 5 V; specified range 4.6–5.5 V |
|---|---|
| Maximum power consumption | 8 W |
| Internal storage | 4 GB, with 2 GB available as listed in the specification |
| Board size / net weight | 174.9 × 101.4 mm / 0.14 kg |
| Working temperature | −40°C to +80°C |
| Working humidity | 0–80% RH, non-condensing |
The bare board is not waterproof. Plan a suitable enclosure and check mounting holes, antenna clearance, power wiring and module-cable access. Keep the existing configuration and program files before replacing a controller.
HD-C16L selection questions
Can the onboard HUB75E ports directly load 650,000 pixels?
V1.0 distinguishes 200,000 pixels for direct loading from 650,000 pixels in a cascaded setup. Use compatible receiving cards and confirm the cabinet arrangement for the expanded load.
Are the PC and Display network ports interchangeable?
They have different documented roles. The 100 Mbps PC port handles configuration, publishing and networking; the Gigabit Display port sends data to receiving cards.
Is 4G supplied as standard?
Wi-Fi is standard in V1.0. The 4G module and RS-232/RS-485 functions are listed as optional, so confirm the required version and accessories before ordering.
Does two-channel 1080P playback mean a 4-million-pixel LED output?
No. Video decoding/window playback and LED pixel loading are separate specifications. Use the direct or cascaded pixel limit when planning the screen.
Contact EagerLED with the screen width and height in pixels, module driver IC and scan mode, direct/cascaded wiring plan and networking requirements. For expanded systems, browse our LED receiving cards and confirm compatibility.
