TFT Feather Wing Enclosure

You can now use the TFT Feather Wing in your 3D printed feather box. This is a great way to make a portable project with a 2.4" TFT display. You'll need an Adafruit Feather, the TFT Feather Wing, and a 500mAh battery (optional).

Prerequisite Guide

Please make sure you've walked through the TFT Feather Wing tutorial before assembling this project – That guide will show you how to install header pins on the header, explains pinouts and software setup.

3D Printed Case for TFT Feather Wing

The enclosure is slightly different than the Feather Box. It's larger because it needs to enclose the entire display and PCB. The topper has a perfect cutout for the display and features the same "snap-fit" functionally – Just press it down on top of the enclosure to install it. The display requires M2.5 machine screws to secure the PCB to the topper.


The case comes in two different versions, one that exposes the Adafruit Feather and the other fully encloses it.


  • feather-tft-case.stl
  • feather-tft-case-slim.stl
  • feather-tft-top.stl

Install TFT Feather Wing to Topper

Start by laying the PCB over the topper with the display facing down and the topper facing up with the standoffs visible.

Orient Screen

Orient the display so the cutout is lined up with the screen. The cutout should only expose the viewing area and not any black borders. 

Mounting Holes

Line up the mounting holes on the PCB with the holes on the standoffs of the topper. The holes in the standoffs are ~2.5mm in diameter and ~4mm deep.

Fasten Machine Screws

Install and fasten a 2.5M 4mm size machine screws into each mounting hole. Hold PCB up against topper and keep it flush while fastening screws.

Secured TFT Display

Check PCB to ensure the TFT display is fully secured to the topper. Flip it over and double check the screen cutout is still properly oriented.

Install Feather to TFT Feather Wing

Now it's time to install the Adafruit Feather onto the TFT Feather Wing. Before we install it, we need to make sure the short header pins are installed on the bottom of the Feather. If you have regular header pins, use wire cutters to trim them short.


Start by orienting the board so the pins line up. Then, lay the board over the female headers and guide the pins into the holes. Press board down until pins are fully seated. The two plastic pieces from headers should be flush with each other.

Slide Switch (Optional)

If you'd like to use a slide switch to power your project on/off, then you'll need to wire up your own. This one is a bit special because the ends of each wire have short right angle header pins – These can easily plug into the second pair of female headers on the back of the TFT Feather Wing. Use the enable and ground pins to power off the circuit. Battery recharging will still be functional.


Thread Wires from Switch

Insert the two wires from the slide switch in between the Adafruit Feather and TFT display – Going through the side with the USB port. Pull the wires through the other end. This will allow us to connect the slide switch to the TFT display without too much excess wiring.

Connect Switch to TFT

Now we can connect the wires from the slide switch to the female headers on the TFT.  Plug in one wire to the enable pin and the other to the ground pin. Note: If the header pins from the switch are too tall, you won't be able to close the case. So, make sure they're low-profile!

Thread Wires from Battery

Next, we'll insert the cable from the 500mAh battery through the opposite side of the feather. Pull the cable through until it's about half way.

Connect Battery to Feather

Now we can plug in the male JST connector from the 500mAh battery to the female JST connector on the Adafruit Feather.

Secure Battery to TFT

You can secure the battery to the back of the TFT Feather wing using a blob of mounting tack. Stick it on the battery and place it on an area away from the on-board reset button and on/off switch.

TFT Feather Assembly

Now our TFT is secured to the topper! Next, we'll work on installing the slide switch (optional) and closing it all up!

Install Switch to Case

Next, we'll work on securing the slide switch to the case. Insert the body of the slide switch at an angle into the three walls inside the case – These will hold the slide switch in pace. The actuator from the slide switch will stick out slightly from the side of the case. 

Install Topper to Case

OK! Now it's time to close it all up. Orient the case so the the cutouts line up in the appropriate spots (microUSB and SD card slot). Then, insert the topper over the top of the case. Press the two parts together until they snap together. Make sure all of the wires all contained within the case! You don't want any of them to get kinked.

Complete Assembly!

Alright, looks like we're all done. Give it a try, test to see if everything works. If you installed the switch, turn it on! Test out battery charging, see if your USB cables connect properly.
