Mounting bar for Max 7219 Led Matrix. Easy to mount longer strips for signs. Holes are a bit tight so you can drill or use a tap to thread M3. You can use the short ones only, but I thing the longer is easier and more rigid when mounting many circuitboards. You can also use stand offs to mount the strip to a panel.

I ran out of screws so there is a lot of screws missing in the pictures.
