PCB provides options for controlling multiple I2C devices on one bus
Another project that I made (JC Pro Macro) features a connector that is supposed to align with the pins of the common .96" OLED screens. Sometimes it does, and other times the GND and VCC pins are reversed. This board takes care of that scenario by swapping the GND and VCC pins back on the first row of pins.
A third row is provided with normal alignment for usage with a "standard" arrangement, and a fourth breaks out the standard arrangement again, but includes normallly-closed solder pads that can be cut as needed to isolate one or more lines.
While you could break out I2C pins yourself with wire/perfboard/solder/etc, there's a good chance you'll end up with a messy end product. This takes care of things for you, just cut traces as needed, solder up the appropriate headers and plug in!
While it's nominally an I2C device, you could use it for any arrangement of pins that you need to break out, reverse, and/or cut power to. You might even use it with an EZ Fan 2 transistor board! Unused lines of pins could be used for a smoothing capacitor, or the I2C pull-up resistors that... other people neglect to attach to their circuits.
