Description
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.

Frequently Asked Questions
What is the difference between IP65, IP67, and IP68?
IP65 handles surface splashes only and is not suitable for UK outdoor conditions or bathroom wet zones under BS7671. IP67 is rated for temporary immersion and covers outdoor garden installations, most bathroom zones, and exposed architectural features. IP68 handles continuous submersion for ponds, fountains, and fully exposed outdoor applications. For most UK garden and decking projects, IP67 is the correct choice.
Can I cut this product to a custom length?
Yes. ATOM LED products can be cut at the marked cut points without voiding the warranty. Many competitors restrict cuts to 50–100mm intervals, which wastes offcuts on tight custom runs. Use sharp scissors or a craft knife for a clean cut, then seal the end with a suitable end cap.
What size driver do I need?
Multiply the total metres by the wattage per metre, then add 20% headroom. For example: 10 metres of 24V neon flex at 9W/m = 90W total, so you need a minimum 108W driver. Never load a driver above 80% capacity for long-term reliability.
Should I choose 12V, 24V, or 48V?
Choose 12V for caravans, cars, boats, and any project powered by a 12V battery. Choose 24V for most home and trade installs where you need dependable run length with lower voltage drop. Choose 48V for longer architectural runs where extra distance and single-feed flexibility matter. For underwater or submerged installs, use IP68 Waterproof lights and the correct driver for that product; do not use 48V underwater.
What is your warranty?
ATOM LED offers product-specific warranties: up to 7 years on single-colour COB strip, 5 years on RGB and RGBW COB strip, and 4 years on LED neon flex. The warranty covers manufacturing defects. Call 01952 370028 for warranty claims.
Do you offer free delivery?
Yes. Free UK delivery on 97% of products via Royal Mail 48-hour tracked. Free next day delivery on Mainland UK orders over £90 (order by 1pm, Mon–Fri).
