HD-W00 LED Sign ControllerSingle-Color Wi-Fi Control Card — 320×32 / 640×16, LedArt APP, 1000 Programs
Huidu HD-W00 single-color Wi-Fi LED sign controller for door lintel screens and store signs: onboard Wi-Fi hotspot for phone updates, 20+ text effects, 1000-program storage, and 3W low-power design — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.

What Is the Huidu HD-W00 LED Sign Controller?
The HD-W00 LED sign controller is a low-cost single-color Wi-Fi control card for door lintel screens, store signs and information displays. The card broadcasts its own Wi-Fi hotspot — a phone or laptop connects to it directly and updates the program through the LedArt APP or HD2018/HD2020 software. No network infrastructure is required.
It stores up to 1000 programs across 20 display areas, with separate special effects and borders per area, and drives single-color LED modules through its HUB12 output.
• Control range: 320×32 or 640×16 pixels (single color).
• Storage: 1MB flash; up to 1000 programs, 20 areas with separate effects and borders.
• Communication: Wi-Fi (phone APP / laptop hotspot connection).
• Effects: 20+ text effects, simple animations, program/region borders, custom borders.
• Sensors: temperature, humidity (P5), brightness (P7), IR remote.
• Power: 3W at 5V DC. Operating temperature: -40°C to +80°C.

Why the HD-W00 Works Without Any Network Infrastructure
The Card Is the Network
Power the card on and it broadcasts a Wi-Fi hotspot. A phone with the LedArt APP connects directly, edits the sign, and walks away — the fastest install path for shop signs where no LAN cable can reach.
20 Independent Areas
One card drives up to 20 display areas, each with its own effects and borders. A typical lintel layout — clock on the left, scrolling message in the middle, counter on the right — is one program, not three devices.
Scheduled Power and Dimming
The timer switch turns the screen on and off automatically, and three dimming modes (manual, automatic, timed) keep the sign readable at night without glare complaints.
HD-W00 Pixel Capacity Calculator: Will Your Sign Fit?
The W00 fits two formats: 320×32 or 640×16. Count your modules before buying.
Example 2 — Does not fit: a two-row sign of 320×64 = 20,480 px — over the height budget. Result: move up to the HD-W60 (1024×32 dual-color) or HD-W62 (1024×64).
General rule: single color only, total pixels within 320×32 or 640×16. Send us your module count for a free load check.
When Should You NOT Choose the HD-W00?
• Your sign needs dual or tri-color modules — the HD-W60 and HD-W62 handle red/green/amber combinations.
• The screen is taller than 32 pixels or wider than 640 — W62 covers 1024×64.
• You need full-color video playback — use the HD-C16C or above.
• You need USB drive updates — the W00 is Wi-Fi only; the W60/W62 add a USB port.
The W00 wins on cost in pure single-color Wi-Fi jobs — outside that box, the bigger W-series cards fit better.

How to Wire the HD-W00 Sign Controller
Two cables power the sign; the rest happens over Wi-Fi.
- Power: 5V DC to the power connector — keep the supply within 4.2–5.5V.
- Display: HUB12 ribbon cable from the card to the LED module chain — keyed connector orientation.
- Sensors (optional): P5 for temperature/humidity, P7 for brightness, plus IR remote support.
- Program: connect phone or laptop to the card’s Wi-Fi hotspot and publish from LedArt / HD2018 / HD2020.
HD-W00 Setup with LedArt APP — Step by Step
Most shops never open a laptop for the W00 — the whole workflow fits in the LedArt phone APP.
- Step 1 — Power the card and wait for the Wi-Fi hotspot to appear.
- Step 2 — Connect: join the card’s hotspot from the phone.
- Step 3 — Open LedArt and detect the card.
- Step 4 — Set the screen: module type and resolution (320×32 or 640×16).
- Step 5 — Edit content: text, clocks, temperature/humidity, counts, lunar calendar — with 20+ text effects.
- Step 6 — Publish to the card over Wi-Fi.
- Step 7 — Schedule: timer power on/off and the three dimming modes.
- Step 8 — Backup: export the program for reuse on other signs.

HD-W00 Common Issues & Diagnostic Procedures
Straight answers from our support engineers’ most frequent HD-W00 LED sign controller tickets.
Q1 How many pixels can the HD-W00 control?
Single-color formats of 320×32 or 640×16 pixels, with 20 display areas, 1000 programs and 20+ text effects.
Q2 Can the HD-W00 run dual-color signs?
No. The W00 is single-color only. For dual or tri-color modules use the HD-W60 or HD-W62, which also add a USB port for program updates.
Q3 How do I update the sign content?
Connect a phone to the card’s Wi-Fi hotspot and publish from the LedArt APP, or use a laptop with HD2018/HD2020 software over the same hotspot.
Q4 Does the HD-W00 support sensors?
Yes – the P5 port takes temperature/humidity sensors, the P7 port takes a brightness sensor for automatic dimming, and an IR remote is supported.
Q5 Can the sign switch off automatically at night?
Yes. The card supports timer-based screen on/off switching plus three brightness adjustment modes.
Q6 What software is used with the HD-W00?
LedArt APP on the phone, and HD2018 or HD2020 on PC. All three connect over the card’s own Wi-Fi hotspot.
