Kawaii means cute in Japanese we based this project on KawaiiTech logo. This pendant is so cute, easy to assemble and re-program which makes it totally customizable, it can be worn as pendant or even earrings. We liked black solder mask with HASL finish, maybe you wanna rock ENIG?


The board is based on ATTINY85 charlieplexing 6 LEDs and powered by a CR1220 battery.


BOM:

1 ATTINY85 SOIC 8

6 0805 LEDs we recommend ultra bright

1 cap 0805 0.1uF

1 CR1220/12225 battery holder, footprint is made for 2894 but should also work with S8201-46R.

1 Switch CUS-12TB


You can generate an Arduino Project and use Arduino UNO board to program it. Or if you have the ICE Atmel programmer use the on board footprint.
