The Koshi Electronics W40 PRO is the flagship 40-port heavy-duty Wi-Fi pixel LED controller. Built on a fast ESP32 dual-core processor, its true parallel architecture drives data out of all 40 ports simultaneously — running large displays up to 16,000 pixels with smooth 24-bit HD animation at a high frame-rate (FPS), no flicker or lag. Controlled fully from your phone or laptop browser — no PC and no app required. Built for mega HD animation walls, building facades, malls and grand stage / festival displays.

🎬 Full Video Tutorial — How to Use the Controller

This video covers everything in detail — connecting the W40 PRO, WiFi setup, IC type, S/Z wiring, matrix size, and running HD video & text, step by step:

Key Features

• 40 true parallel ports — all update simultaneously for smooth HD animation, fast text and flawless playback.
• Up to 16,000 pixels (40 ports × up to 400 LEDs per port).
• 24-bit colour animation at the highest frame-rate in the range (ESP32 dual-core, no dropped frames).
• Multiple matrix folders on one SD card — keep programs for different matrix sizes on a single card and choose which one to play from your phone.
• Multiple IC support — WS2812B (GRB), WS2811 (RGB), UCS1903 (RGB), correct colour order per chip.
• S-Type & Z-Type wiring — for both text and animation.
• 100% phone controlled — built-in Wi-Fi web portal, no app to install.
• Live multi-language text — Hindi, English, Urdu, Arabic, Marathi, Tamil and more.
• Background effects & borders — Rain, Snow, Fire, plus 20+ animated border styles.
• microSD .out animations (made with Jinix software) with Text + Animation auto mode.

📁 Multiple Matrix Folders — One SD Card, Many Sizes

Older controllers held a program for only one layout per card — to run a different display size, you had to rebuild the whole card. The W40 PRO removes that limitation.

Who benefits most?

• 🏢 Professional installers — every building and site has a different layout. One card works everywhere.
• 🎪 Event & decoration companies — every client's display is a different size. No card swapping.
• 🧪 Testing — try different sizes from a single card and pick the one that looks best.

Specifications

Compare the Range — Pick by Project Size

Every model plays smooth 24-bit colour animation and runs the same easy phone-browser control. The difference is scale and frame-rate (FPS):

*All four models play 24-bit colour animations — only the frame-rate (FPS) differs: lowest on the W1000 PRO, highest on the W40 PRO. Actual FPS also depends on the LED load (pixels per port).

👉 Why W40 PRO? 40 true-parallel data lines spread your pixels across more separate runs — the highest FPS and smoothest 24-bit HD animation for the biggest, most spread-out installations. Need fewer ports? See the W16000 / W8000 / W1000 PRO.

Best For

• Mega matrix screens & HD animation walls
• Large commercial building outlines & mall lighting
• Grand wedding arches & premium stage backdrops
• High-end DJ lighting & nightclub visuals
• Big Thoran & festival decoration setups

How It Works

1. Connect a heavy-duty 5V SMPS and wire your pixel strings across the 40 output ports.
2. Power on and connect your phone to the WiFi network W40_PRO_XXXX (password 12341234).
3. Open http://10.10.10.10 in your browser (it usually opens automatically).
4. Select your matrix folder, IC type, LEDs-per-port and connection type (S/Z). If the card holds several matrix folders, choose the one you need here.
5. Type your text and press Send, or load .out animations from the SD card.

Power Supply (SMPS) — How Many You Need

Frequently Asked Questions

How many pixels does it support?
Up to 16,000 pixels — 40 ports with up to 400 LEDs per port. The control panel warns you if a layout exceeds the limits.

What does "true parallel" mean?
All 40 ports send data at the same time, so even very large displays play 24-bit animation at a high frame-rate — smooth, with no flicker.

How much power supply do I need?
Use about one 5V 80A (400W) SMPS per ~1,000 LEDs — e.g. 2 for a ~2,000-LED setup (50X40, 100X20) and 4 for a ~4,000-LED setup (100X40). See the Power Supply guide above.

How do I create my own animations?
Animations (.out files) are created on a PC using Jinix software, then exported as .out and copied onto the SD card. Only Jinix .out files are supported.

Can I play different matrix sizes from one SD card?
Yes. For each size, create a folder on the SD card named Height × Width + S/Z — for example 50X40S — and place that size's .out files inside it. Select the folder in Matrix Layout; you can keep as many size folders as you like on one card.

Which LED ICs are supported?
WS2812B (GRB) and WS2811 / UCS1903 (RGB). Select the IC type that matches your physical strip.

Colours look wrong (red shows as green)?
You've selected the wrong IC type — switch between WS2812 (GRB) and WS2811 / UCS1903 (RGB).

The display is mirrored or scrambled?
Switch the Connection Type between S-Type and Z-Type.

How is it different from the W16000 PRO?
Both drive up to 16,000 pixels and play 24-bit animation, but the W40 PRO has 40 true-parallel ports (vs 16) — so it runs at a higher frame-rate (FPS) and spreads pixels across far more separate data runs, ideal for the most demanding, widely-spread installs.

I forgot my WiFi password.
With the controller on, hold the BOOT/RESET button for about 8 seconds — the panel flashes red and the password resets to 12341234.

Warranty

6-month warranty* on manufacturing defects.

*Warranty covers manufacturing defects only. Not covered: physical damage, water damage, wrong SMPS connection (reverse +/− polarity), connecting to 220V AC, or the controller being exposed to rain. Protect the controller and SMPS from rain (use a rainproof box outdoors).
