Designed for Large Displays
With 12,750 pixel capacity and 700 watts of dual power supply headroom, the MD1500 Baldrick17 xConnect is built to handle the demands of dense mega trees, multi-zone roofline runs, and synchronized show installations. Dual Mean Well LRS-350-12 supplies keep every output stable under full load, from the first pixel to the last — all season long.
Built on the same controller platform at the heart of Mattos Designs mega tree and show kits, the xConnect version is the natural choice for builders already running xConnect infrastructure. Every output is labeled with Mattos Designs Deez Nuts high-visibility injection-molded numbered ID hardware so your cables are organized and identifiable from day one — no guessing, no tracing wires.

Key Features
Pixel Control
- 17 outputs — up to 750 pixels per port at 40 FPS
- Total capacity: 12,750 pixels
- Compatible with WS281x, RGBW, UCS1903, SM16703P, UCS2904, and more
- Individually fused 7.5A outputs with LED fault indicators per port
Power Management
- Dual Mean Well LRS-350-12 supplies — 350W each, 700W total
- 10 AWG high-temp silicone wire for safe high-current operation
- Independent power banks (4 + 4 + 4 + 4 + 1) for balanced voltage distribution across outputs
- Terminal covers on both PSUs for safe, protected AC connections
Connectivity
- Waterproof RJ45 bulkhead coupler — plug in your network cable without opening the enclosure. Dust cap seals the port when not in use. A 3D printed PETG interior storage mount keeps the coupler body secured inside the enclosure lid during off-season — always where you left it when you need it.
- Single 10/100 Ethernet port
- Supports E1.31, sACN, DDP, Art-Net protocols
- Direct xLights integration — push your configuration straight from xLights 2024.10 and later. No FPP license required.
- Static IP mode — assign a fixed IP address without a DHCP server for reliable deployment in the field
Cable Management
- xConnect pigtails pre-installed on all 17 outputs — plug-and-play ready for xConnect pixel strings and extensions
- Mattos Designs Deez Nuts injection-molded numbered ID hardware (1–17) included — high-visibility, durable, and purpose-built for xConnect pigtail identification
Enclosure & Weatherproofing
- Mattos Designs MD1500 high-impact thermoplastic alloy enclosure with self-latching hinged cover, weather-resistant seal, and integrated mounting system
- Nylon cable glands route all pigtail cables cleanly out of the enclosure
- Stainless steel hardware throughout for corrosion resistance
- ⚠ Mounting requirement: The MD1500 enclosure must be mounted vertically with pigtails exiting downward to maintain its weather-resistant rating. Horizontal or inverted mounting is not recommended and may void the weather resistance.
Build Quality
- 3D printed PETG backer plate with integrated Baldrick board standoffs — precision-fit for the MD1500 interior
- Staggered PSU stacker brackets keep both power supplies offset for clear terminal access without removing either unit
- 3' SJTW 14/3 outdoor-rated power cord — properly gauged for the load, built for outdoor conditions
- Every unit fully wired and tested before shipment
