Firmware
This keyboard runs standard QMK firmware, configuration for which is included in this repository.
Build with support for VIA enabled:
sh
qmk compile -kb sf2040 -km via
The RP2040's bootloader can be accessed by holding the ESC key while plugging in the keyboard. Then, simply drag-and-drop the output .uf2 firmware into the bootloader folder.
This keyboard has been merged into the QMK repository and VIA's keyboard repository, meaning that it is fully compatible with the VIA online keyboard configuration software (usevia.app)
For more information about setting up and working with QMK keyboard firmware, read the QMK documentation (https://docs.qmk.fm).
