PCB Hardware

Use the following hardware to secure the Feather to the PCB mounting plate.

  • 4x M2.5 x 6mm (female-female) Standoffs
  • 8x M2.5 x 4mm screws

Installed Hardware

Insert the screws through the four mounting holes and install the standoffs. Reference the photo for correct placement.

Install Switch

Place the switch into the built-in holder. Insert the body of the switch at an angle and press down to secure in place.

Install Feather

Place the Feather over the four standoffs and line up the mounting holes. Adjust the wiring so they're neatly fitted under the Feather. Insert and fasten 4x M2.5 x 4mm long screws through the mounting holes to secure the Feather.

Faceplate Holder Hardware

Use the following hardware to secure the faceplate holder to the enclosure framing.

  • 6x M2.5 x 6mm (female-female) standoffs
  • 6x M2.5 x 4mm screws

Install Hardware for Faceplate Holder

Insert the screws through the six mounting tabs and install the standoffs. Reference the photo for correct placement.

Test Fit PCB

I suggest test fitting the PCB mounting plate before securing it to the framing. That helps determine the orientation of the enclosure. 

Holes in Frame

The hole cutout on the side of the enclosure framing is used to expose the microUSB port on the Feather and the slide switch.

Installing Strips

The two NeoPixel strips are secured to the inner walls of the framing using nito double-sided tape. Hot glue or other adhesives can also be used as a substitute.

Cut Tape Pieces

I cut out four strips of double-sided nito tape. That was enough to secure the NeoPixel strips.

Install Strip A

The PCB mounting plate is removed in order to have more space for the NeoPixel strip to be attached. Check the wiring and ensure there's enough slack for the strip. Reference the photo for best placement. Attach the strip to the inner wall of the framing.

Install Strip B

Attach the second strip the other side of the framing. Check the wiring and ensure there's enough slack for the strip. Do not cover up the snaps. Try to place the strips in line with the inner wall.

Test Strips

Plug in the battery to the Feather and use the slide switch to power on the circuit. This lets you know if everything is still working and if the placement of the strips are good.

Install Faceplate Holder & PCB mount

Place the faceplate holder down with the standoffs facing up. Place the framing over the faceplate holder and line up the mounting holes. Place the PCB mount over the three mounting tabs onto the inside of the framing. Use the following hardware to secure the parts together. Use the longer screws to secure the PCB mounting plate.

  • 3x M2.5 x 6mm long screws
  • 3x M2.5 x 4mm long screws

Secured Plate Holder

Reference the photo for correct placement of the faceplate holder, PCB mounting plate and framing.

Connect Battery

Plug in the 1200mAh battery into the JST power port on the Feather.

Tack Battery

The battery is secured to the back cover using mounting tack.

Secured Battery

The battery can be fit onto the bar in the middle of the back cover.

Install Back Cover

The back cover snap fits onto the back of the framing.

Back Cover Mounting Brackets

The back cover mounting brackets are used for attaching 3M velcro strips. This allows the sign to be easily taken off the door or wall. Use the holes built-into the back cover to secure onto screws or nails.

Install Acrylic Plate

Insert the acrylic plate into the faceplate holder by sliding into the rails.

Install Front Cover

Place the front cover over the framing with the side tabs properly oriented. Firmly press together to snap fit shut.

Final Build

And there you have it! You sign is ready to mount onto the wall or door. I plan to use this a whole lot and hope this inspires you to check out CircuitPython!
