T12K-U-200 and T20K-U-200 Software: Multi-Channel Special Controllers

The T12K-U-200 and T20K-U-200 trade long outputs for many short ones: 12 or 20 outputs of 200 LEDs. That suits “firework” bursts, kite and star shapes, or any design made of many small elements that each need their own cable.

In LEDEdit Pro 2026

• T12K-U-200: 12 outputs × 200 LEDs.
• T20K-U-200: 20 outputs × 200 LEDs.
• 15 chip profiles each, with RGBW and DMX512 options.

Example: a firework burst with 16 rays

Sixteen rays of 180 LEDs each, every ray on its own output of a T20K-U-200:

• Draw one ray with Draw LEDs or a 1 × 180 Pattern Builder stamp.
• Repeat on ports p1…p16 — each port shows 180 of 200 used.
• Animate with chasers and Auto Animate Burst or Cascade to fire the rays one after another (timeline guide).

Tips

• Plan outputs first: 200 LEDs fill up quickly.
• Use one layer per group of rays so you can time them separately.

Chip profile notes: WS2811 / WS2812B

Both special controllers list WS2811 among their 15 profiles (and WS2818B for the break-continuation variant) — same 800 kHz single-wire 24-bit RGB as the T-U series. For most firework/kite stars use WS2811 for WS2811 or WS2812B pixels, and set colour order GRB for WS2812B, RGB for WS2811. Swapped reds/greens = wrong order, not wrong chip — see wrong colours fix. For white-enhanced bursts pick TM1914 / TM1814 / SM16704 (3 RGBW profiles per controller) and for DMX tails use DMX512 250K/500K/750K. The remaining 800 kHz/48-bit profiles are SM16703, UCS1903, P9883, GS8206, 1916, TM1926, TX5806. All 15 are export-ready per data/lep_controllers.json families ledit2026_t12k_u_200 and ledit2026_t20k_u_200.

5-step export to SD card (T12K / T20K-U)

1. Plan outputs — Decide rays vs kite tails: 16 rays of 180 LEDs = 16 outputs on a T20K-U-200 (180 of 200 each). In LED Layout Creator set Max LEDs/port = 200 and place each ray on its own port p1…p16 with Draw LEDs or a 1×180 Pattern Builder stamp.
2. Animate per ray — Give each ray or group a layer, run Auto Animate Burst/Cascade from the timeline guide, and preview the burst in per-LED preview — see the video tutorial for the live workflow.
3. Pick chip — Output → Export LEDEdit .led → family T20K-U-200 (or T12K-U-200) + chip WS2811 for WS2812B stars, TM1914 for RGBW, or DMX512. Set colour order and FPS.
4. Preflight & write — The dialog lists 16 used outputs, 180 LEDs per port and scenes. Export the package, then Write to SD Card or copy the .led files.
5. Test — If a ray stays dark, check the 200-per-port limit — 200 LEDs fill fast — and see last LEDs dark and SD-card not playing. For legacy firework controllers, use DXF + AVI fallback.

T12K-U-200 / T20K-U-200 in LEDEdit Pro 2026

Data from the app's controller catalog. "LEDs per output" is the export profile's pixel limit; also check your controller's manual.

1. Map your LEDs in the LED Layout Creator or import a DXF layout, with one port per controller output.
2. Build the show with layers, clips and scenes on the timeline.
3. Open Output → Export LEDEdit .led…, choose the T12K-U-200 / T20K-U-200 family and the chip type of your pixels.
4. Check the preflight (controller, chip, colour order, scenes, frame rate, outputs, LEDs) and click Export.
5. Copy the files to the SD card, or use Output → LEDEdit Tools → Write to SD Card….
