LTECH DMX-SPI-203 DC5-24V DMX512 SPI 1024 Digital Pixels IC Decoder Controller

The LTECH DMX-SPI-203 is a professional DMX to SPI LED controller designed to control digital pixel LED strips. It supports a wide range of compatible ICs including WS2811, WS2812, WS2801, TM1803, TM1804, TM1809, TM1812, UCS1903, UCS1909, UCS1912, UCS2903, UCS2909, UCS2912, TLS3001, TLS3002, LPD6803, LPD1101, LPD8803, LPD8806, P9813 and more.

The controller supports the international standard DMX512/1990 protocol and offers two operating modes: DMX Management Mode and DMX Decode Mode. In DMX Management Mode, users can select built-in programs including speed, brightness, direction and effect types directly via DMX console. In DMX Decode Mode, users can program and control every LED channel individually using a DMX512 console.

With a 0–100% dimming range and up to 540 built-in changing modes, the DMX-SPI-203 allows full control over colour, speed, brightness and dynamic lighting effects. It features an OLED display for easy configuration and supports remote matching via the M203 RF remote. The controller can manage up to 1024 pixels and supports virtual pixel expansion from 1 to 6 times.

This controller is suitable for architectural lighting, stage lighting, pixel matrix displays and large scale digital LED installations.
