Firmware

To update the firmware, follow these steps:

Double-tap the reset button on the left half of the keyboard. Alternatively, bind &bootloader to any key using ZMK Studio and press it.
Connect the left half to your computer via USB-C cable. It will appear as a removable drive, similar to a flash drive or camera.
Drag and drop the left.uf2 file onto the drive to update the firmware.
Repeat the process for the right half of the keyboard.

Note: You typically only need to update firmware if you want to adjust sleep timeouts or enable home row mods.
