The DD11 backplanes are a series of UNIBUS and MUD backplane system units. They were normally installed in a BA11 mounting box.
- DD11-A backplane - 4 slot UNIBUS, powered through a power connector board plugged into the backplane
- DD11-B backplane - 4 slot UNIBUS, with early DEC power distribution connectors
- DD11-C backplane - 4-slot MUD, with later power distribution connectors
- DD11-D backplane - 9-slot MUD
- DD11-P backplane - modified DD11-D used to hold the PDP-11/34 CPU
