+The json file can contain multiple profiles. Each profile requires a name and different parameters. If one parameter is not set, the default value, as compiled into the firmware is used. The example above shows all the currently supported values. Others may follow. A sample file with a lot of boards can be found [here](pin_mapping.json). This means you can just flash the generic bin file and upload the pin_mapping.json file. Then you select your board and everything works hopyfully as expected.
