All parts were purchased at Yusha Kobo in Akihabara. He seems satisfied with having built it. Since the soldering is amateur work, contact may become poor with use, but please re-solder it yourself. Used a few times. I think there are some minor scratches. Magic Split is based on QMK firmware, so you can customize the keymap to your liking. Features: • Split design: Allows for input in a natural posture, matching shoulder width. • Compact layout: Designed to minimize the number of keys and expand the operational range through layer switching. • Low-profile switches: Looking at the photos from the side, it uses thin "Kailh Choc" type low-profile switches, which are thinner than regular mechanical switches. • Equipped with an OLED display: Can display input layers and status.
