This weeks project is making Cappy from Mario Odyssey.

The Adafruit Monster M4sk has everything we need to make this project.

With the Monster M4sk, you can customize the eyes to match the theme of your character.

It's really easy to edit the configuration file and make it look how you want! Just open a file in a text editor. You can change things like the size and color of the iris.

The PCB is designed so that you can break the two eyes apart and bring them closer together.


The Monster M4sk features a splittable design! This allows you to cut along the perforations on the PBC to separate the two eyes. the Two boards are then connected via a JST SH 9-Pin cable.

We can even create a longer wire to increase the distance even further like we did with the longer antenna eyes!

The Adafruit Monster M4sk packs a ton of awesome stuff into one single board. It’s running a Cortex M4, it has 8 megabytes of flash storage, USB charging and 2x IPS TFT LCD displays. It also has buttons, light sensor, expansion ports and accelerometer.
