Know before you buy
The keezyboost40 is sold as a bare PCB only. You will need to source your own switches, keycaps, stabilizers, and a USB-C cable to complete the build.
Yes, the LCD screen is integrated into the PCB design. However, as this is a DIY component, you should be comfortable with basic assembly and firmware configuration to get the display running.
While the board supports both, it is intended for enthusiasts who are comfortable with custom keyboard firmware. You will need to be prepared to compile and flash your own keymap to make the board functional.
The product description specifies this as a bare PCB component. Unless otherwise noted in your specific kit configuration, you should expect to solder your switches directly to the board.
The 4x10 ortholinear layout aligns keys in a grid rather than the traditional staggered rows. It is highly efficient for those who prefer a compact, ergonomic setup, but it does require a learning period to adjust your muscle memory.
The keezyboost40 uses a standard USB-C interface and is compatible with Linux. Because it runs on the RP2040 controller, it acts as a standard HID device once the firmware is flashed, requiring no special drivers.
