The payload consists of a Raspberry Pi A+ (single-board computer), to which are connected various sensors. There are two electronics boards: one blue, about 10 cm x 10 cm is size with a second smaller green board (the Raspberry Pi) mounted on top. Various wires, connectors, resistors and other electronic components are sandwiched between the electronics board and a transparent plastic plate, which is attached via four posts/screws at the corners. There is also a clear plastic box, with a clasp on one side, containing a variety of small, coloured beads. Another set of four posts/screws connects the entire device to the lid of the container in which it resides. The lid forms part of a small, green rectangular box. The container has various logos, writing, stickers and barcodes on its four sides, including logos for Cuberider and Nanoracks. There is also a small round velcro dot, which would have been used to secure the container to the walls of the ISS in zero gravity. Attached to the box is a manila tag labelled 'JSC Project Parts Tag' and stamped in red with 'FLOWN HDWR'.
