Huidu HD-C36C LED Control CARD

Product Overview

What Is the Huidu HD-C36C LED Control CARD?

The HD-C36C is a full-color asynchronous LED control card that integrates sending-card, receiving-card and Wi-Fi functions on a single PCB, per Huidu Specification V0.1 (20210408). It drives up to 524,288 pixels (1024×512, widest 8192), carries ten HUB75E interfaces so it drives a small or medium screen as its own receiving card, and manages content through the HDPlayer software, the PingZhangKong mobile app and Huidu’s cloud platform — the same one-card architecture as the HD-C16C, at two and a half times the loading.

The C36C is the middle rung of Huidu’s full-color card ladder: the HD-C16C at 204,800 pixels for small screens, the HD-C36C at 524,288 for small-and-medium screens, and the newer C16L generation above. Beside the cards, the HD-A3 player boxes cover the external-box form factor, and the HD-W62 cards cover single-dual color. Unify LED is an LED screen manufacturer supplying Huidu control systems at factory level — this page uses the official HD-C36C Specification V0.1 as its data source.

Specifications

What Are the HD-C36C LED Control CARD Specifications?

Specifications from the official Huidu HD-C36C Specification V0.1 (20210408).

Data Note — Exclusive

Why Is the HD-C36C Spec Cleaner Than the C16C’s?

On the HD-C16C page, we documented the first “official vs official” conflict on this site: the C16C’s V0.1 datasheet lists 120,000 pixels while the current Huidu page lists 204,800 — a firmware evolution. The C36C has no such conflict:

The reading is straightforward: the C36C shipped at its full loading from the start — 1024 × 512 = 524,288, and 8192 × 64 = 524,288 exactly — so there was no later upgrade to create the version split the C16C experienced. The two remaining listing variations are minor: a few sellers quote the working temperature as -30°C to +70°C (official V0.1: -20°C to +80°C) and a weight of 0.3 kg (official ~0.12 kg). Official V0.1 wins both.

One market note that does deserve attention: at least one listing marks the C36C as discontinued. Huidu’s official sources make no such note, and the C-series has grown newer generations (C16L and beyond) — treat the status as “current per official sources, confirm availability at order” and ask us for the live position before quoting a large order.

Comparison

Which Full Color Control Card Do You Need: HD-C36C or HD-C16C?

The two cards share one architecture; the difference is the loading budget:

Table A — The Full-Color Card Ladder (Official Specs)

Table B — Card vs Box vs Single-Dual (same site map)

Selection guide: up to 204,800 pixels — the HD-C16C; up to 524,288 pixels or an 8192-wide lintel — the HD-C36C; beyond that or an external box — the HD-A3 family. The step from C16C to C36C costs roughly USD 10–30 in the market range and buys 2.56× the pixels — the cheapest loading upgrade in the Huidu line.

Core Features

What Does the HD-C36C LED Control CARD Do?

Six capabilities from the official V0.1 define how the C36C behaves in the field:

Interface

Which Ports Are on the HD-C36C LED Control CARD?

Board interfaces from the official V0.1:

• 5 V DC power — single low-voltage feed, 8 W draw.
• 100 Mbps RJ45 input — program updates and LAN/cloud access.
• USB 2.0 — U-disk updates and storage expansion.
• Test button — module test patterns.
• Sensor port — temperature, humidity, brightness.
• GPS port — location services (optional).
• 1 Gbps RJ45 output — cascade to HD-R receiving cards for larger screens.
• Stereo audio output — 3.5 mm standard.
• 10× HUB75E — module interfaces; the card works as its own receiving card.
• Relay terminals — remote power control wiring.

Mounting note: like the C16C, the C36C has no enclosure — the conformal-coated PCB lives inside the LED cabinet, protected from direct rain, dust and condensation.

Loading Capacity

How Big a Screen Can the HD-C36C Control Card Drive?

The official budget is 524,288 pixels in a 1024×512 configuration, widest 8192, highest 1024. The width limit divides exactly: 8192 × 64 = 524,288. Translated into real screens (UnifyLED conversion):

The extreme shape is the C36C’s signature: an 8192-pixel ultra-long lintel — at P4, 32.77 m wide × 0.26 m tall, driven by one card. That is the configuration the official ultra-long lintel case demonstrates, and it is the reason integrators step past the C16C (whose 8192-wide budget leaves only 64 pixels of headroom at 204,800 ÷ 8192 = 25 high).

The per-port arithmetic, one more time: the 1 Gbps output port carries the receiving-card chain at the 655,360-pixel-per-port ceiling documented across this site — the C36C’s 524,288 loading is what the ten HUB75E interfaces handle directly. Larger canvases step to the HD-A3 player box.

Applications

Where Is the HD-C36C Control Card Used?

The C36C serves the small-and-medium full-color screens that live inside cabinets — and the lintel class where the 8192 width limit pays off:

• Door lintel screens — the classic C36C install; the official 0:15 case shows a standard lintel, and the 0:20 ultra-long case shows the 8192-wide budget in action.
• Small and medium commercial screens — the official 0:33 case covers the class from poster displays to mid-size signage.
• Storefront and window displays — one card, one cabinet, Wi-Fi content updates from the app.
• Multi-store synchronization — the RF module keeps several C36C screens on the same program across stores.
• Remote-managed signage fleets — relay power control plus cloud management turns a fleet of screens into one dashboard.

Huidu HD-C36C LED Control CARD: The Complete Buying Guide (2026)

The Huidu HD-C36C LED Control CARD is the middle rung of Huidu’s full-color card ladder — and the cleanest spec sheet in the family: its V0.1 datasheet lists 524,288 pixels and every marketplace agrees, which is exactly the opposite of the sibling HD-C16C, whose datasheet and current page disagree. This guide rebuilds the C36C from the official V0.1 document, explains the one-card architecture and the 8192-wide lintel capability, walks the C16C-to-C36C upgrade decision, and positions it against the player-box and single-dual-card lines on this site.

Chapter 1 — The Full-Color Card Ladder

Huidu’s full-color card line climbs three rungs: the HD-C16C at 204,800 pixels for small screens, the HD-C36C at 524,288 for small-and-medium screens, and the newer C16L generation above. The ladder is a pure loading decision, because the architecture is identical across the rungs: sending card plus receiving card plus Wi-Fi on one PCB, ten HUB75E interfaces, 4 GB storage, relay power control, 8 W draw. The C36C is the rung most lintel and storefront projects land on — it covers the 1024×512 class outright, and its 8192-pixel width limit is what makes ultra-long lintels a one-card job.

The C36C also marks the point where Huidu’s card line and box line start to overlap: a 524,288-pixel canvas fits either a C36C card inside the cabinet or an HD-A3 box outside it. The card wins on part count and cabinet cleanliness; the box wins on serviceability and the path to HDMI sync. The async player guide walks the mounting trade-off; this page covers the card side.

Chapter 2 — The Clean Spec Story: Why the C36C Has No Version Split

On the HD-C16C page we documented the first “official vs official” conflict on this site: the C16C’s V0.1 datasheet lists 120,000 pixels while the current Huidu page lists 204,800 — a firmware evolution that still confuses listings. The C36C has none of that: the V0.1 datasheet lists 524,288 (1024×512) and marketplace listings agree. The arithmetic is exact in both readings: 1024 × 512 = 524,288, and 8192 × 64 = 524,288. The C36C simply shipped at its full loading from the start, so there was no later upgrade to split the record. The only variations that survive are minor — a -30°C to +70°C temperature reading on some listings (official V0.1: -20°C to +80°C) and a 0.3 kg weight (official ~0.12 kg). Official V0.1 wins both.

The lesson the two cards teach together is worth carrying into every Huidu quote: when a datasheet and the live product page agree, the spec is the product; when they disagree, the version history explains it. The C16C’s split was a firmware evolution, the C36C’s consistency was a launch at full spec — and both are documented on this site, so a buyer checking either page gets the same discipline: read the current official page, treat the datasheet as the baseline, confirm the live figure at order time.

Chapter 3 — 524,288 Pixels: The Arithmetic and the Screens

The C36C’s numbers are the same per-port arithmetic that anchors every Huidu document on this site. The 1 Gbps output port carries the receiving-card chain at the 655,360-pixel-per-port ceiling; the C36C’s own 524,288 loading is what the ten HUB75E interfaces handle directly. In meters: 4.10 m × 2.05 m at P4, 5.12 m × 2.56 m at P5, 8.19 m × 4.10 m at P8, or 10.24 m × 5.12 m at P10. The extreme shape is the signature: 8192 pixels of width at 64 high — at P4 that is a 32.77 m ultra-long lintel driven by one card, the configuration the official ultra-long lintel case demonstrates.

The storage planning follows the same discipline as the C16C: 4 GB onboard holds roughly four hours of HD video per gigabyte, and the U-disk port extends it as far as the drive goes. A lintel running full-width promotions with occasional full-video loops fits comfortably in 4 GB; image-heavy campaigns plug in a U-disk as part of the storage budget. The 8 W draw means the control side of the screen costs less than a single LED module to run — the same number at twice the loading of the C16C.

Chapter 4 — One Card, Three Roles: Same Architecture, More Loading

The C36C collapses three devices onto one PCB exactly as the C16C does. As a sending card, it stores programs in 4 GB of flash and pushes content to HD-R receiving cards over the 1 Gbps output. As a receiving card, its ten HUB75E interfaces drive modules directly. As a Wi-Fi module, it is standard, with the PingZhangKong app. The one-card economics scale with the screen: a medium lintel install replaces a sending card, a receiving card, a Wi-Fi module and a timer/relay — and the relay removes the timer device most installs bolt on anyway. The 8 W draw means the control side costs less than a single LED module to run.

Chapter 5 — The Lintel Class: Where the 8192 Limit Pays Off

The C36C’s practical home is the lintel class — door-top banners, storefront fascias and the ultra-long screens that run full-width promotions. The 8192-pixel width limit at 64 high is exactly 524,288, so an ultra-long lintel uses the card’s full budget with zero waste; the C16C, at 204,800, can only drive 25 pixels of height at that width, which is too thin for most content. The official case videos show both the standard and the ultra-long lintel installs. For width-hungry projects, the width limit — not the pixel count — is the binding constraint, and the C36C is the rung that clears it.

Two lintel field notes from installers. First, the height budget at 8192 wide is exactly 64 pixels — a full-width lintel is a single-row-plus design, so content should be built for a thin banner (text, logo strips and tickers), not full video. Second, the HUB75E wiring on a 8192-wide screen spreads the canvas across the ten interfaces in columns; keep the ribbon assignments matched to the cabinet layout and the smart-setting wizard handles the rest. The test button cycles the module test patterns before any content is sent — run it first, the way the C16C guide recommends.

Chapter 6 — The Upgrade Decision: C16C or C36C?

The step from the HD-C16C to the C36C is the cheapest loading upgrade in the Huidu line: roughly USD 10–30 in the market range for 2.56× the pixels. Three conditions justify it: the screen plan crosses 204,800 pixels; the project is an 8192-wide lintel where the C16C leaves only 25 pixels of height; or the integrator wants the same one-card architecture with headroom for future content. Below 204,800 pixels with no lintel ambitions, the C16C saves the money. Above 524,288, the HD-A3 player box or the C16L generation takes over.

The RF sync option applies to the C36C exactly as it does to the C16C: a fleet of lintel screens across stores runs one campaign from a master, with no network at each site. For a retail chain standardizing on the C36C, the RF module plus the cloud platform gives two independent fleet paths — RF for same-network sync, cloud for internet management — and the relay closes the loop by powering the fleet down overnight. The same one-card economics multiply across the fleet: every additional lintel adds one card and nothing else.

Chapter 7 — The Market Note: Discontinued or Not?

One marketplace listing marks the C36C as discontinued; Huidu’s official sources make no such note. The practical reading for a buyer: even in the worst case — the C36C aging out of the line — the same one-card architecture survives in the C16L generation, and the 10× HUB75E wiring, the HDPlayer workflow and the PingZhangKong app carry over unchanged. The card you standardize on today is not a dead end even if the model number rotates. The honest reading: the C-series has grown newer generations (C16L and beyond), and sellers sometimes mark older SKUs as discontinued when the newer line launches — without the manufacturer confirming it. The buying discipline is the same as every Huidu product on this site: confirm availability against the current official line at order time, and ask for the live position before quoting a large order. Unify LED confirms the model status with the factory at every quote.

One more buying note specific to the C-series: the older C36 (without the C suffix) uses a 2-wire 50-pin HUB interface, while the C36C uses the ten-wire HUB75E universal interface — listings that mix the two describe different boards. When a spec sheet says “C36C,” check the HUB interface matches HUB75E; that single detail decides whether the card plugs into the modules you already have.

Chapter 8 — Price, Warranty and the Buying Checklist

Verified August 2026 pricing: USD 95 at jekazled.com, factory-direct on request. Unify LED is an LED screen manufacturer in Changsha, China, supplying control systems alongside modules, cabinets and power supplies as one assembly — the C36C ships tested against the modules it is specified for, with a 2-year warranty and the CE/FCC/RoHS copies on request.

Final checklist for the procurement email: (1) state the pixel budget and shape — 524,288 at 1024×512 with the 8192-wide limit decides the C36C vs the C16C or the A3 tier; (2) confirm the model is current with the factory before large orders; (3) state the module type and interface so the HUB75E wiring is planned; (4) confirm whether the relay power control will be used and the power-path wiring; (5) list any sensors (temperature, humidity, brightness) and the GPS option; (6) state the screen count — fleets order the RF sync module for multi-store campaigns; (7) order one spare per ten installed — the card is the cheapest component in the chain and the spare beats the site visit.

The spare logic is the same as the C16C but the fleet is usually bigger: a chain of lintel screens loses one display per failed card, and at USD 95 the spare is cheaper than the service call to diagnose it. Because every C36C in a fleet runs the same configuration surface, one spare stands in for any screen in the network — ten minutes of swap, zero missed programming. For a chain running fifty lintels, two spares and a bench test on arrival is the standard operating procedure we recommend.

Conclusion. The Huidu HD-C36C LED Control CARD is the middle rung of Huidu’s full-color card ladder — and the cleanest spec sheet in the family: 524,288 pixels (1024×512, widest 8192) with no version split, ten HUB75E interfaces that make it its own receiving card, 4 GB storage, relay power control, Wi-Fi and cloud management, 8 W draw and a conformal-coated PCB built for the cabinet. It is the C16C’s architecture with 2.56× the loading, at the cheapest upgrade price in the Huidu line — the card for the lintel class and the medium screen. Confirm availability at order, wire the relay for the energy win, plan the 8192-wide content as a thin banner, and the C36C runs the lintel fleet on one card per screen.
