## Bootloader

Enter the bootloader in 4 ways:

* **Physical reset button**: Hold the "BOOTSEL" button on the back of the PCB and briefly press the "REBOOT" button on the back of the PCB.
* **Top side reboot pads**: Bridge the reboot pads on the top of the PCB with a pair of tweezers twice in a row, quickly.
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
