Know before you buy
No, this PCB is specifically designed for Kailh Choc v1 low-profile switches. It features hotswap sockets that are only compatible with the Choc v1 footprint.
Yes, you can build it for wireless use by installing a nice!nano controller. The board includes an onboard power switch and a dedicated battery connector to facilitate a wireless setup.
The Sea Picro RP2040 is intended for wired-only builds and offers high performance, while the nice!nano is required if you want to enable Bluetooth wireless connectivity.
The PCB supports an integrated rotary encoder, but it is typically sold as a separate component. You will need to source a compatible encoder and knob to complete that section of the board.
The column-staggered design aligns the keys with the natural reach of your fingers, which can reduce wrist strain and improve comfort compared to a traditional row-staggered layout. It may require a short adjustment period if you are coming from a standard rectangular keyboard.
Beyond the PCB, you will need a compatible controller (RP2040 or nice!nano), 44 Kailh Choc v1 switches, 44 keycaps, a rotary encoder, and a battery if you are building a wireless version.
