WS2812B/SK6812 Addressable RGB Mini Round PCB – Single-Pixel Control, Solder-Any-Wire Freedom
Model: ADY-2812-01-9305
Title: WS2812B/SK6812 Addressable RGB Mini Round PCB – Single-Pixel Control, Solder-Any-Wire Freedom
Subtitle: 100 LEDs/pcs, one LED one pixel, direct solder pads lower the DIY barrier.
Product Overview
If you have used LED strips, you have probably run into these problems: fixed spacing, hard-to-bend corners, and re-soldering after cutting.
The WS2812B/SK6812 programmable RGB mini round PCB is designed to solve those limits.
Each mini round board is an independent pixel. The back side has 3 pads, which is 5V, Din or Dot, and GND, so you can solder wires directly—any length you need: 100 mm, 200 mm, around a curve, or across a fabric seam. No proprietary connector cables required. Cut a Dupont wire and solder it.
Key Features
- 100 LEDs/pcs, one LED one pixel: a full panel of 100 individually addressable LEDs.
- Break-apart panel: snap off as many LEDs as you need and keep the rest for later.
- Direct solder pads(3-Pin): 5V, Di/Do, GND; choose your own wire length.
- WS2812B and SK6812 compatible: shared single-wire protocol and support for FastLED / WLED ecosystems. Learn one, use both.
- SK6812 RGBW option: independent white channel for cleaner video and photography fill light, helping reduce rolling stripes and banding on camera.
- Standard lead spec: Min. 40 mm total lead length—35 mm insulated wire, 2.5 mm stripped and tinned at each end.

Why It Lowers the DIY Barrier
Traditional LED strip: fixed pitch, pressure connectors, difficult corners.
Mini round PCB: single-pixel control, free wire length, free layout. Irregular surfaces, inside models, collars, wristbands, shoes—route wires to fit the structure.
LED strips solve continuous light. Mini round boards solve free-layout light.
Three-Line Quick Start
Arduino + FastLED core three lines:
FastLED.addLeds<WS2812B, 6, GRB>(leds, 1);
leds[0] = CRGB::Red;
FastLED.show();WLED users can configure the output as WS2812B / SK6812 and start using it right away.
Who It’s For
- Education / beginners: cut, solder, and light up.
- Makers / geeks: fast prototyping without custom connectors.
- Wearables / costumes: thin, lightweight round boards that can be sewn or glued.
- Models / props: corners where LED strips cannot bend.
- Photo / video: SK6812 RGBW independent white channel for cleaner fill light.
FAQ
Can I cut the panel?
Yes. The panel is break-apart, so you can snap off the number of LEDs you need and keep the rest for future projects.
What wire can I use?
Any suitable thin wire for 5V, Din or Dot, and GND.
Is it compatible with WLED?
Yes. Configure it as WS2812B or SK6812 in WLED. It also works with FastLED and common Arduino / ESP32 setups.
Do you offer RGBW?
Yes, the SK6812 RGBW version includes an independent white channel, which is useful for photography and video fill light.
Can I order samples or bulk quantities?
Yes. Contact us with your target quantity, LED type, and application. We can support samples, wholesale orders, and OEM/ODM projects.
Power Note
Addressable LEDs can draw significant current at full brightness. Use a stable 5V power supply with enough current for your LED count, and connect grounds properly. For larger installations, power injection and fusing are recommended. Contact us if you need help estimating power.
Final Thoughts
The WS2812B/SK6812 addressable RGB mini round PCB makes programmability the baseline—and solder-any-wire freedom the real low barrier to entry.
