You will need:

- Male to Female jumper cables

- AVR programmer (  I used Pocket AVR programmer from sparkfun )

- USB micro cable for the programmer

-USB OTG cable

-All 3D printed parts

-M3 x 10 CSK screws

-Silicone button pads

The brains of Tipo is basically the same AVR 32u4 chip used in the Arduino Leonardo. We use the arduino leonardo bootloader to make programming easier, via the USB type A directly. 

Use the pocket AVR programmer to upload the Arduino Leonardo bootloader. This guide should help:

Arrange the Buttons inside the Enclosure Top

Arrange the silicone pads inside, on top of the buttons

Carefully place the PCB inside, taking care to not disturb the pads

Put the other half of the clampshell on, and fasten with M3x10 fasteners
