PCB Revision 1 (bootmapper client)
If you downloaded a QMK file, please extract it into your QMK/keyboards directory. After that you can use the linux command "make pearl" or "make pandora" to make the appropriate hex file. Simply flash the hex file afterwards and you are good to go! Pandora is already on the QMK repo and via will automatically load as well.
For via with pearl, you must be using a second generation GREEN pcb. When flashed, open via and select "Show design tab" in the settings tab, and then load the json file linked below in the design tab, while your Pearl is connected.
