Install Speakers
Line up the mounting holes on the side of the enclosure with the ones on the speakers. Insert the speaker into the frame and position it so it’s lined up with the speaker cut out. Insert four #4-40 machine screws into the mounting holes on the frame.
Mount Speakers to Enclosure
Place a hex nut into the screw and hold it in place while you fasten the screw until it's tight. You can do this to only two screws or all four - it's pretty secure with just two.
Thread Standoffs
You'll want to fasten #4-40 machine screws into the standoffs on the bottom cover. This will actually thread the threads and open up holes to make it easier to fasten later.
Mount Pro Trinket
You'll want to loosen the two mounting holes on the Pro Trinket (the ones in front, close to the microUSB connector). I used #4-40 falt phillips screws (the sharp pointy kind) to do this. Fasten the screw slowly to avoid breaking the PCB.
Place the Pro Trinket onto the bottom cover and match up the standoffs. Hold the PCB in place while you fasten two #4-40 screws into the bottom cover.
Mount Audio FX soundboard
The mounting holes on the audio FX soundboard PCB is a bit more open, but I recommend making the threads, so fasten machine screws into the two mounting holes up front and than take them out.
Place the Audio FX soundboard ontop of the standsoffs on the bottom cover. Insert the two #4-40 screws and fasten the PCB to the bottom cover.
Insert Trellis PCB through Enclosure
Place the Trellis through the bottom of the enclosure. The bottom has the port cut outs.
Close bottom cover
Place the bottom cover over the enclosure frame. Line up the microUSB connectors with the cut outs on the enclosure.
Secure bottom cover
Hold the bottom cover in place. Insert and fasten four #4-40 3/8 flat phillips machine screws into the corner mounting holes on the bottom cover.
Install Slide Switch
Unsolder the two wires on the slide switch from the Pro Trinket Lipo backpack add-on. Insert the switch into the cut out on the side of the enclosure with the wires going in first. Press the slide switch into the cut out. Apply a bit of adhesive to perminently mount it in place. Don't forget to solder the wires from the slide switch back onto the Pro Trinket lipo backpack.
Plug in Power
At this point you'll want to connect the JST cable from the 1200mAh lipo battery to the Pro Trinket lipo backpack. Place the lipo battery into the enclosure.
Install Trellis
Check the edges of the PCB for any sharp bits. Smooth them out using a filing tool. Place the Trellis PCB onto the tray and press it down to snap it in place.
Lay the tray on top over the enclosure frame and press it down until it rests on the inner lip.
Elastomers & Cover
Orient the nubs on the elastomers with the proper holes on the Trellis PCB. Lay the keypad over the PCB and lightly press it down.
Place the cover over the elastomers and press it down until it snaps into the enclosure.
Insert and fasten four #4-40 3/8 flat phillips machine screws into the mounting holes.
