📋 Specifications

🔧 Pinout Reference (Advanced Users)

Everything comes pre-configured in WLED — you never need this for normal use. But if the board is ever reset, reformatted, or reconfigured by mistake, this table lets you (or any technician) restore every setting yourself in Config → LED Preferences. Apna controller, apni marzi — koi lock nahi! 💪

⚙️ How It Works

1. Connect your pixel strip's Data + GND to any of the 8 output taps, and connect board power (5V–24V — match your strip's voltage).
2. (Optional, recommended) Wire your SMPS through the relay output — the power supply will switch ON/OFF automatically with your lights.
3. Power on and connect your phone to the WiFi network KOSHI_WLED_PRO (password koshi1234). The control page opens automatically (or open http://4.3.2.1).
4. Set LED count and IC type per output in Config → LED Preferences.
5. Enjoy 180+ effects, enable Sound Reactive for music sync, or point a 24-key IR remote at the board for instant control.

❓ Frequently Asked Questions

Do I need to install an app?
No — everything runs in your phone browser. The official WLED app is optional.

LITE ya PRO — which one should I buy?
If your setup is simple 5V pixels — the LITE is perfect. If you need 12V/24V support, built-in music reactivity, relay automation, IR remote, sensors, or per-output Data + GND taps — the PRO is for you. Baaki options se comparison ke liye: Best WLED Controller in India →

What is the Data + GND tap?
Every output gives you both Data and GND together — essential for stable signals on longer wire runs. This is a PRO-exclusive feature.

Does it have a proper level shifter?
Yes — a 74AHCT245 gives true 5V logic on all 8 outputs for flicker-free data. This is the #1 thing cheap imported boards skip.

Do I need a separate mic for music reactive?
No! The PRO has an INMP441 I2S digital microphone built onboard — far cleaner than cheap analog mic modules.

What does the relay output do?
It switches your SMPS ON/OFF automatically with your light state — saving electricity and removing the need for a separate switch.

Preset file upload ya settings page kaam nahi kar raha?
Jab aap board ke WiFi se judte hain toh ek popup window apne aap khulti hai — usme file upload block hota hai (ye phone/laptop ki limitation hai, board ki nahi). Us popup ko band kariye aur Chrome ya Edge kholkar address bar mein http://4.3.2.1 type kariye. Ab sab kuch normal chalega.

Board reset/reformat ho gaya — settings kaise wapas laayein?
Upar diya Pinout Reference table dekhiye — Config → LED Preferences mein wahi GPIO numbers daal dijiye (Output 1 = GPIO 17, Output 2 = GPIO 16...) aur mic/relay/IR ke pins bhi table mein diye hain. 2 minute mein board bilkul factory jaisa configure ho jayega. Detailed steps PDF manual mein bhi hain.

Is the IR remote included?
The IR receiver is built into the board. Any standard 24-key LED remote works — available separately at very low cost.

What can I connect to the sensor port?
LDR for auto day/night lighting, PIR motion sensors, buttons, and DIY modules — tutorials on our YouTube channel.

Can it run 12V or 24V strips?
Yes — the board accepts 5V–24V DC input. Always match the supply voltage to your strip's rating.

How do I update the software?
Over WiFi (OTA) — no USB cable needed, ever.
