๐ก Kitni LEDs Chala Sakte Hain? (LED Capacity Guide)
Ye sabse zyada poocha jaane wala sawaal hai โ iska poora jawab yahan hai:
| Total LEDs (all 8 ports) | Performance |
| Up to 500 LEDs | โก 60+ FPS โ ekdum smooth, sabse best |
| 500 โ 1,000 LEDs | โ ~40 FPS โ smooth, recommended range |
| 1,000 โ 1,500 LEDs | ๐ ~25 FPS โ chalega, effects thode slow |
| 1,500+ LEDs | โ ๏ธ Effects lag karenge โ 2 controllers use kariye (WLED sync feature se dono ek saath chalenge) |
Per port: 300โ500 LEDs tak aaram se chalti hain โ koi hard limit nahi. Aap chahein toh ek port par 500 aur baaki ports par kam bhi rakh sakte hain.
๐ 8 Ports ka asli fayda โ LEDs baant kar lagaiye!
WLED saare ports par ek saath (parallel) data bhejta hai. 800 LEDs ek hi port par = slow effects. Wahi 800 LEDs ko 8 ports par 100-100 baant dijiye = 8 guna tez aur smooth! Isi liye humne 8 outputs diye hain โ zyada LEDs bhi, aur speed bhi.
โก Asli limit power hoti hai, controller nahi: Har LED full white par lagbhag 60mA leti hai (5V par). Matlab 500 LEDs โ 30A ka SMPS. Iska hisaab WLED khud bhi bata deta hai โ Config โ LED Preferences mein total LEDs daaliye, recommended power supply dikh jayega. Aur lambi strips mein har 3โ5 meter par power injection dijiye, warna aakhri LEDs dim/peeli dikhengi.

โ๏ธ How It Works
- Connect your pixel strip's Data + GND to any of the 8 output taps, and connect board power (5Vโ24V โ match your strip's voltage).
- (Optional, recommended) Wire your SMPS through the relay output โ the power supply will switch ON/OFF automatically with your lights.
- 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).
- Set LED count and IC type per output in Config โ LED Preferences.
- Enjoy 180+ effects, enable Sound Reactive for music sync, or point a 24-key IR remote at the board for instant control.

๐ Firmware Update โ Zaroori Jaankari / Important
โ Naye boards ab WLED v16 ke saath aate hain. In par v16 โ v16 ke updates WiFi (OTA) se bilkul normally chalte hain โ koi cable nahi chahiye.
โ ๏ธ Lekin agar aapke board mein purana WLED v0.15 hai (pehle khareeda hua board), toh use WiFi se v16 par update MAT kariye โ board permanently kharab (brick) ho sakta hai.
Apna version 10 second mein check kariye: WLED page kholiye โ Info โ wahan firmware ka naam dikhega.
โข KOSHI_PRO_v16 โ aap v16 par hain, sab theek hai. WiFi updates safe.
โข KOSHI_PRO_v1.1 ya KOSHI_PRO โ aap v0.15 par hain. Neeche wali baat aap par laagu hoti hai.
Technical wajah: WLED v16 naye ESP32 core (Arduino-ESP32 2.x / ESP-IDF 4.4) par bana hai, jismein alag bootloader aur partition layout hota hai. OTA update sirf application image badalta hai โ bootloader ko replace nahi karta. Isliye purane v0.15 bootloader ke upar v16 image chadhte hi board boot hona band kar deta hai (WiFi/lights dead).
v0.15 se v16 par jaane ka sahi tarika: board ko USB-to-TTL programmer se, onboard PROG header ke through flash karna padta hai (pehle Erase, phir full factory image @ 0x0). Ye ek baar ka kaam hai โ uske baad v16 โ v16 updates WiFi se normally chalte hain. Zaroorat ho toh humein WhatsApp kariye โ hum guidance ya pre-flashed board de denge.
In English: New boards now ship with WLED v16, where OTA (WiFi) updates within the v16 series work normally. If your board is still on the older v0.15 firmware, do NOT update it to v16 over WiFi โ v16 uses a newer bootloader that OTA cannot replace, so the board will fail to boot. Check your version under Info in the WLED page; moving a v0.15 board to v16 requires a USB programmer via the PROG header (erase, then write the full image at 0x0).
โ Frequently Asked Questions
Per port kitni LEDs chala sakte hain?
Har port par 300โ500 LEDs tak aaram se chalti hain. Saare 8 ports milakar 1,000 LEDs tak best smooth performance milti hai (~40 FPS), aur 1,500 tak bhi chal jata hai. Iske upar 2 controllers use kariye โ WLED ke sync feature se dono bilkul ek saath chalenge.
Saari LEDs ek hi port par laga dein toh?
Chalengi, lekin effects slow ho jayenge. WLED saare ports par ek saath (parallel) data bhejta hai โ isliye 800 LEDs ko 8 ports par 100-100 baant dena 8 guna tez hota hai. Yahi 8 outputs ka asli fayda hai. Zone-wise control (har port ka alag effect) bonus mein milta hai!
Kitna bada SMPS chahiye?
Har LED full white par lagbhag 60mA leti hai โ matlab 500 LEDs โ 30A. Exact hisaab WLED khud bata deta hai: Config โ LED Preferences mein total LEDs daaliye, recommended power supply dikh jayega. Tip: SMPS hamesha zaroorat se 20โ30% bada lijiye.
Lambi strip mein aakhir ki LEDs dim/peeli kyun dikhti hain?
Ye voltage drop hai โ lambi strip mein aakhir tak poora voltage nahi pahunchta. Ilaaj: har 3โ5 meter par power injection dijiye (SMPS se seedha strip ke beech/aakhir mein +/โ wires). Controller ka isse koi lena-dena nahi.
Do I need to install an app?
No โ everything runs in your phone browser. The official WLED app is optional.
LITE ya PRO โ which one should I buy?
If your setup is simple 5V pixels โ 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 โ the PRO is for you. Baaki options se comparison ke liye: Best WLED Controller in India โ
What is the Data + GND tap?
Every output gives you both Data and GND together โ essential for stable signals on longer wire runs. This is a PRO-exclusive feature.
Does it have a proper level shifter?
Yes โ 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 โ far cleaner than cheap analog mic modules.
What does the relay output do?
It switches your SMPS ON/OFF automatically with your light state โ 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 โ 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 โ settings kaise wapas laayein?
Upar diya Pinout Reference table dekhiye โ Config โ 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 โ 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 โ tutorials on our YouTube channel.
Can it run 12V or 24V strips?
Yes โ the board accepts 5Vโ24V DC input. Always match the supply voltage to your strip's rating.
How do I update the software?
Naye boards (WLED v16): seedha WiFi/OTA se โ koi cable nahi chahiye. OTA password (default: koshiota) Config โ Security & Updates mein daaliye. Purane boards (WLED v0.15): unhe WiFi se v16 par MAT le jaaiye โ major version ka OTA bootloader badal nahi sakta, isliye board kharab (brick) ho sakta hai. Uske liye USB programmer chahiye. Apna version Info page par check kariye โ poori detail upar "Firmware Update โ Zaroori Jaankari" section mein hai.
Alexa, automatic timers, music sync, 2D matrix kaise use karein?

๐ก๏ธ Warranty
6-month warranty* on manufacturing defects.
*Warranty covers manufacturing defects only. Not covered: physical damage, water damage, wrong SMPS connection (reverse +/โ polarity beyond protection limits), connecting to 220V AC input, or the controller being exposed to rain, or a board rendered unbootable (bricked) by an unsupported firmware update such as a cross-major-version OTA (e.g. v0.15 to v16). Protect the controller and SMPS from rain (use a rainproof box outdoors).
