A TRRS cable is also included, so if you provide keycaps, key switches, and a 34mm trackball, you can start using it immediately with your USB C cable. *Initial defect warranty for one week. *For those who can procure their own case, we can sell the pre-soldered PCB only.

The pro micro is type C and is fixed using con-through connectors. (Con-through connectors cost about 1000 yen for just 4. We spend money on small parts.) Soldering the pro micro's pin headers makes it difficult to remove the microcontroller. The trackball PCB is also fixed using genuine L-shaped con-through connectors. (Trackball PCB can be reused) If you are looking for a split keyboard like Keychron Q11 or BAROCCO MiSTEL MD600, please consider this. Split keyboard Pre-soldered
