Keyball39 Pre-soldered PCB, Black

Hot-swappable, custom-designed keyboard by yowkees (split keyboard)

Keyball39 (also compatible with 44 and 61) on a black PCB.
All components except Pro Micro, OLED, and LEDs are pre-soldered.
This PCB is designed for those who already use Keyball, allowing them to switch without soldering.

*However, switching without soldering is only possible if the Pro Micro and trackball board are connected via con-throughs.

The following items are pre-soldered to the PCB:
→ Chip diodes
→ 14 jumpers
→ 44 switch sockets
→ 2 OLED pin sockets
→ 2 TRRS jacks
→ 2 tactile switches
→ L-shaped con-through soldering

Trackball reading board and sensor are not included, but can be added for an additional 5000 yen.

This is essentially a build-it-yourself PCB that requires almost no soldering.

Keyball44 is +500 yen and Keyball61 is +1000 yen due to the different number of sockets and diodes.

A FR4 top plate (black) is available for an additional 1000 yen.

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

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

For a two-handed ball setup, it's +11000 yen (includes two trackball board sensors and a two-handed ball board).

The following items are needed to complete the build (additional items can be discussed):
① OLED cover (acrylic or 3D printed)
② Middle acrylic (or 3D printed part, or something to fill the gap)
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 cases and other parts from vendors on Mercari, etc., and easily build your own custom Keyball without any soldering.

For cases like those sold by noesis2023, which are divided into top and bottom sections, the top part can be covered by the case, eliminating the need for a top plate.

Thank you.
