The 1553BPCB is a prototype printed circuit board shaped to fit 1553 series handheld enclosures in sizes "B" and "C". Electronics developers and hobbyists use it to build and test circuits that drop straight onto the enclosure's molded PCB bosses without cutting a custom board.

The board is high quality FR4 glass epoxy, with lead free etched copper and a flux coating for easy soldering. Holes of 0.042 in are drilled on 0.1 in centers for standard through-hole parts, and mounting screws are included. The part page lists the size as 4.3 x 2.4 x 0.06 in (109 x 61 x 2 mm); the drawing outline is 109.14 x 60.86 mm with 3.20 mm mounting holes.

Note the compatibility limit: the 1553BPCB is not compatible with battery compartment versions of the enclosure. It suits the regular 1553B single end panel models and the 1553C size. The series notes the board comes from BusBoard Prototype Systems (BPS).

It ships shrink wrapped with a shipping weight of 0.05 lbs (0.02 kg) and is RoHS and REACH compliant. For 1553 size "D" enclosures, the matching board is 1553DBPCB.
