Purpose
Prototyping aid that allows selectable pull-up and series resistors for the I2C bus. To use, just insert the module into your circuit/breadboard and select the appropriate series/pull up resistor values with the solder jumpers. Bridging the jumpers is very easy and switching usually just requires a swipe with the soldering iron.
Purchasing
The I2C Pullup Breakout is available through Leeman Geophysical by emailing John R. Leeman at kd5wxb@gmail.com.

Questions
How big is the I2CPullupBreakout PCB?
It measures 33 × 24.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the I2CPullupBreakout use?
18 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the I2CPullupBreakout KiCad files?
From the jrleeman/I2CPullupBreakout repository on GitHub, at the commit this page was made from: the board is I2CPullupBreakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the I2CPullupBreakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrleeman before reusing the design.
