A circuit board retainer and support apparatus has a first board including a first side and an opposed second side. It also has a first multi-board clip extending from the first side, with the first multi-board clip including a first short spacer block having a short support surface located a first height above the first side, a first long spacer block having a long support surface located a second height above the first side, and a first securing flange, having a first barb with an engagement surface that is a third height above the first side. Also, the first long spacer block is located adjacent to the first securing flange and the first short spacer block is located adjacent to the first long spacer block and farther from the first securing flange than the first long spacer block. The first multi-board clip may also include a second barb extending from the securing flange in an opposed direction from the first and a second securing flange and barb extending from the second side of the first board. With such a circuit board retainer and support apparatus, multiple circuit boards may be retained in spaced relation to each other.
