eInk Gizmo Parts
The eInk Gizmo is designed to be bolted on top of the Circuit Playground (Express and Bluefruit versions). To make the ornaments portable, use a 350mah battery – It is small enough to fit in between the PCBs and should have enough power for several hours.
Place the 350mAh battery in the center of the PCB with the battery cable pointing towards the audio connector (opposite side of the USB label). The battery is small enough to fit in between the standoffs.
Install Circuit Playground
Place the Circuit Playground Express over the standoffs with the USB port lined up with the USB label. The PCBs are secured with M3 x 6mm machine screws (included with the E-Ink Gizmo). In order for the Gizmo and CPX to fit the 3D printed ornament, use only 10 screws. Reference the photo for the correct placement of screws.
Place the 3D printed mount over the PCBs. The edge of the CPX will snap fit into the sides of the mount. Press the mount into the CPX so it is flush with the PCB. Reference the photo for correct placement.
The USB port on the CPX is accessible for programming. The 3D printed mount features a notch to accommodate USB cables.
The top half of the 3D printed ornament is placed over the eInk Gizmo. Line up the hook loop with the USB port on the CPX. Fit the snaps of the top half with match one on the mount. Press the two halves together to snap them them. Start with one side first and work your way to all three.
The top half features open top and bottoms to allow for a modular design. The front cover can be easily swapped for a different color or updated design.
The JST connector from the battery can be directly plugged into the battery port on the CPX. The battery cable is just long enough (25mm / 1in) to reach. It can be pulled out to cut power from the eInk Gizmo and CPX. The cable can also be tucked under the notch on the edge of the mount.
Place the top cover over the display. Orient the cover so it's lined up correctly with the screen. Press the edges to snap fit them together. Start with one side and work your way through all four.
