We strongly recommend this method. If the PCB is not soldered with switches at the moment, use anything that's metal (twizzers for example) to short the (0,0) position key ("ESC" in our PCB) while plugging the USB in. * **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead * **Keycode in layout**: Press the key mapped to `RESET` if it is available Make example for this keyboard (after setting up your build environment): make blaster75:default Flashing example for this keyboard: make blaster75:default:flash See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
