From the project

Lunakey - This is a brand for keyboards designed by Yoichiro Tanaka.

This project has some keyboards designed by Yoichiro Tanaka.

Lunakey Mini is a 40% keyboard which has 44 keys and is splitted to left and right. Each side has 3 rows x 6 columns and 4 keys that are pressed by a thumb. Also, it has an ability to light up by Underglow LEDs on the bottom, an ability to display information by OLED modules and an ability to play a sound by a speaker module. Of course, the column-staggered key layout is the result of deep thinking to fit each finger and each key naturally. Lunakey Mini can assist your PC life everyday.
