Lunakey mini

Lunakey Project

This project has some keyboards designed by Yoichiro Tanaka.

Lunakey Mini

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.

Lunakey Pico

Lunakey Pico 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 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.

The special feature of this Lunakey Pico is that Raspberry Pi Pico has been adopted. Users can use some firmwares: KMK Firmware and PRK Firmware.
