      You can extend grove cables easily using the I2C bus expansion. Just plug in two grove cables.

      I like your idea of allowing sensors to be ordered with multiples of two on one board when each of the sensors just uses one control line. They make Grove Y cables that allow you to connect two sensors to one Grove port on your Grove Shield, but that still leaves the extra real estate being used for the two sensor boards.

      For I2C controllers and sensors, it would be cool to be able to configure and select multiple devices on one I2C board. This would be even easier to implement with the use of my idea to have I2C sub-addresses.

          It would also be nice to have all I2C devices have a second I2C connector so they can be daisy chained like the old SCSI devices had. If all manufacturers just adopted this practice, the standard for I2C would evolve to include it.

          Two grove connectors and an eight bit DIP switch, and the extra code to check for a sub address would not be that much to add for the ability to use multiples of each board at no additional expense to the manufacturer (having to purchase multiple I2C address registrations).

          Already existing I2C sensors and controllers should still work, they would just respond to all calls to their I2C address regardless of sub address. Host software could sort this out and know that all commands to boards with sub addresses are also going to have their commands acted upon by the device that doesn't support sub addresses. As users, we would have to be aware of this and only use the older I2C (non sub address capable) boards only with other I2C boards that have different I2C addresses.

            I have cancelled many orders because of the super high shipping costs...
