Plastic Encasing Removal and Assembly Procedures
The CHUB uses a molded plastic encasing to protect the PCB. Removing and assembling the
plastic encasing requires some care since there are no screws used in the assembly of the PCB and
the plastic encasing. Refer to Figure 4 for a Top and Bottom view of the CHUB plastic enclosure.
4.2.1
Plastic Encasing Removal
The CHUB is shipped pre-assembled. The following section briefly describes the procedure for
removing the plastic encasing.
To remove the Top portion of the plastic case, the user must orient the CHUB so that the bottom
label is facing the user (upside down). Take ahold of the four corners of the Top portion of the
encasing and gently extend the sides away from the Bottom portion. This extension will cause the
Bottom portion of the encasing to free itself from the Top portion. Gently lift the Bottom portion
out, one side at a time, until the Bottom portion is completely detached from the Top portion. This
frees the PCB from the grooves located on the sides of the Top portion.
Once the top portion is removed, the PCB will sit on the bottom portion. To remove the PCB from
the Bottom portion, the user must gently extend the sides away from the Bottom portion, starting
with the side of the PCB containing the USB connectors. Once this side of the PCB is out of the
Bottom portion of the encasing, the user can lift the PCB out at a 25° angle. Be careful of the
placement of the toggle switch in respect to the Bottom portion. Pulling out the PCB without
angling it may cause damage to PCB and the Bottom portion.
4.2.2
Plastic Encasing Assembly
This section briefly describes the procedure to assemble the Top and Bottom portions of the plastic
enclosure to the PCB.
Place the PCB into the Bottom portion, as depicted in Figure 4, at a 25° angle, placing the toggle
switch into its Bottom portion opening. Extend the opposite side of the Bottom portion enough to
lower the PCB into the Bottom portion. Both the toggle switch and USB connectors should fit snug
into their respective openings on the Bottom portion.
Note: Be careful with the LED. The user may have to adjust the LED once the above procedure is done.
This can be done by gently pushing the LED into its Bottom portion opening.
Starting from one side, extend the Top portion such that the Top portion grooves can be placed
onto the PCB within the Bottom portion. Perform this procedure on the second side so that both
grooves on the Top portion sides are firmly holding the PCB in place. Gently push down until the
PCB snaps into place, and the Bottom and Top portions are reassembled.

Component Specifications
The CHUB uses off-the-shelf components. Refer to the specific manufacturer's datasheet for
component specifications. See Section 5.0, "Bill of Materials".
