+
+miniDivide is a split keyboard with 0.8u (16mm) key pitch.
+The size of a single key is 80% of that of a conventional keyboard key.
+Although the key size is more compact than usual, it has the advantage of requiring minimal finger movement.
+The number of keys is 19 keys for one hand and 38 keys for two hands.
+
+It is small and thin, making it easy to carry around.
+The option to mount a coin cell battery on the PCB is available so that the BLE Micro Pro can be installed.
+OLED can also be mounted.

+キー数は片手で19キー、両手で38キーとなります。
+
+小さく、薄いので持ち運びにも便利です。
+またBLE Micro Proを搭載できるよう、コイン電池をPCBに搭載するオプションが可能です。
