Keyball44 Almost Fully Soldered PCB by Shirogane Labo

Self-made keyboard designed by yowkees, supporting hot-swapping
(Split keyboard)

Keyball44 black PCB
All components except Pro Micro, OLED, and LEDs are soldered.
This is a board designed for those who already use Keyball, allowing them to switch without soldering.
If you already have a Pro Micro, you can assemble it directly.

*However, you can only switch without soldering if the Pro Micro and trackball board are connected via con-throughs.

The following items are pre-soldered to the board:
→ Chip diodes
→ 14 jumpers
→ 49 switch sockets
→ 2 OLED pin sockets
→ 2 TRRS jacks
→ 2 tact switches
→ L-shaped con-through soldering

The trackball reading board and sensor are not included, but you can purchase them here, allowing you to complete the build.

This is essentially an assembly board that requires almost no soldering.

If you need a FR4 top plate (black), it's an additional +1000 yen.

Please note that the delivery time may vary depending on the product.

Pro Micro soldering with con-throughs is an additional +3000 yen, and an OLED display is +1000 yen.

For a two-handed ball setup, it's an additional +1200 yen (for the two-handed ball board), but you'll need two trackball reading boards.

The following items are required to complete the build. (Additional items can be discussed)
① OLED cover (acrylic or 3D printed)
② Middle acrylic (or something 3D printed to fill the gaps)
③ Bottom (acrylic or case)
④ Trackball case
⑤ Screws, spacers
⑥ Pro Micro (con-through installed)
⑦ Trackball reading board

Of course, you can purchase a case, etc., from someone selling them on Mercari, etc., and easily build your own custom Keyball without any soldering.

If you use a case like the one sold by noesis2023, which is divided into a top body and a bottom, you won't need a top plate.

Thank you.
