I will create custom pixel led panels with embedded esp32 web control firmware
About this Gig
Welcome to custom Pixel LED panel hardware design and serverless ESP32 web control!
Looking to build a custom addressable LED panel, custom matrix display, or interactive light fixture? I offer full end-to-end design, combining physical PCB matrix layout with optimized ESP32 firmware featuring an embedded, mobile-responsive web server.
No external cloud or server required! The ESP32 hosts its own local web interface and Access Point (AP), allowing direct control from any smartphone, tablet, or PC browser.
What I Offer:
- Hardware & PCB Design: Custom addressable LED matrix panel layouts (WS2812B, SK6812, etc.), power distribution traces, and level-shifting logic.
- Embedded Async Web Server: Light-speed, responsive local UI built into the ESP32 using Async WebSockets for zero-latency control.
- Custom Effects & Modes: Color pickers, brightness control, custom animation modes, speed control, and state memory persistence across reboots.
- Software Environment: Clean, repository-ready VS Code + PlatformIO codebase using the Arduino framework.
Deliverables:
- Production-ready PCB files (Schematic, Gerber, BOM, Pick-and-Place)
- Step-by-step flashing, assembly, and user instructions
Platform:

FAQ
How does the serverless interface work without internet or cloud?
The ESP32 creates its own local WiFi Access Point (AP) or connects to your existing WiFi network. It directly serves a self-contained HTML/JS web interface hosted entirely inside its internal flash memory. You just connect to the network, open a web browser, and control your lighting in real time.
What addressable LED types do you support
I support all common single-wire and two-wire protocols including WS2812B, WS2813, SK6812 (RGBW), APA102, and WS2811, as well as high-density LED matrix panels using FastLED or Adafruit NeoPixel libraries.
How do you handle high current and power distribution on custom PCB layouts?
High-density LED panels draw significant current. I design custom PCB layouts with wide copper traces, multi-point power injection pads, onboard filtering capacitors, and dedicated 3.3V to 5V logic level shifters to eliminate flicker and ensure high stability.
Do I get full support to test the code and hardware?
Yes! I test the logic on physical ESP32 boards on my end, and I provide step-by-step remote support to assist you while you flash the code, set up the web UI, and assemble your hardware until the project is 100% successful.
