HUB75 P2.5 64x32 brackets

P2.5 64×32 LED Panel Brackets

These brackets turn a pile of P2.5 64×32 HUB75 panels into one solid, flat LED wall. They screw into the threaded mounting holes on the back of the panels and hold every seam aligned, so the picture runs across panel edges without gaps or steps. Neighboring brackets lap over and under each other and share screws, so the whole frame locks together. The same six bracket shapes build a wall of any size: just print more of them (see "How many do I need?" below).

Drops into place. Most parts have holes for the alignment pins on the back of the panels, so each bracket sits in exactly the right spot before you put a single screw in.

Protects the edge LEDs. The LEDs along the outside edge of a panel, especially at the corners, are easy to knock off, and a knocked LED stays dark. The corner, side and top/bottom pieces have a raised lip that wraps the edge of the wall and takes the bumps instead.

Built and tested on a 3 × 2 wall of Muen P2.5 64×32 panels (480 × 160 mm, 192 × 64 pixels).

Print the test template first. Panel makers don't all put the mounting holes and pins in the same place. Hold the template (160 × 80 mm, one panel) against the back of one of your panels: if the holes line up with the panel's screw holes and pins, every bracket will fit. It's a thin flat plate that prints quickly and saves you from printing a full set that doesn't match.

What's included

• Middle: joins four panels where their corners meet.

• Side left / Side right: the left and right edges of the wall.

• Top/bottom: the top and bottom edges.

• Corner left / Corner right: the outside corners.

• Power supply mount: holds an A-200AF-5XZ 5 V supply on the back of the wall. It sits on top of one middle bracket and shares its screws, so it fits any wall 2 × 2 or larger.

• Test template: checks the hole and pin pattern of your panels.

• Board mount: holds a HUB75 Bridge on the back of the wall. It sits on a middle bracket and shares its screws, like the power supply mount.

Driving the wall.

I run these walls from the HUB75 Bridge, a 4-port Ethernet controller I make for HUB75 panels: it takes video from xLights or any DDP source and runs 16 panels of 64×64 at 60 fps. It's on Tindie. The board mount above fits it.

How many do I need? For a wall W panels wide and H panels tall:

• Corner left: 2, Corner right: 2

• Side left: H − 1, Side right: H − 1

• Top/bottom: 2 × (W − 1)

• Middle: (W − 1) × (H − 1)

Example, 3 × 2 wall: 2 + 2 corners, 1 + 1 sides, 4 top/bottom, 2 middle (12 parts).

Hardware (3 × 2 wall with the power supply mount)

• 34 × M3×8 screws: 30 for the brackets, 4 to hold the power supply on the mount

• 6 × M3×14 screws: through the power supply mount, through the middle bracket under it and into the panel. Use these in place of that middle bracket's six M3×8.

• 4 × M3×14: through the board mount,  through the middle bracket under it and into the panel.

• The power supply mount's two extra holes are for panel alignment pins, not screws.

• Board mount: 4 × M3×6 to hold the board; it uses the middle bracket's screws to hold it to the wall

Print settings (what I used)

• PETG, 4 walls, 4 top and 4 bottom layers, 25% infill

• Print each part flat side down, as it comes in the file.

• Supports from the build plate on: Middle, Side left, Side right, Corner right, Top/bottom. The lap steps where parts overlap hang 3 mm above the bed.

• No supports: Corner left, Test template, Power supply mount, Board mount.
