* **Make sure your PCB uses an `atmega32u4` before flashing!** A PCB that uses an `APM32F103CBT6` with `uf2boot` has been shipped with some extras purchases and to replace some defective units. Flashing that PCB with "rev1" firmware may result in a non-functional PCB which can only be recovered using a hardware programmer (e.g. an ST-Link V2)

## Bootloader
Enter the bootloader in 3 ways:
* **Bootmagic reset**: Hold down the top left key and plug in the keyboard. This will also clear EEPROM, so it is a good first step if the keyboard is misbehaving.
* **Physical reset**: Short the set of vertical holes on the third row, to the right of Caps Lock. These can be reached with tweezers after the board has been assembled.
* **Keycode in layout**: There is no key mapped to `QK_BOOT` in the pre-created keymaps, but you may assign this key in any keymaps you create.
