Daisy Chainable I2C Level Shifter

An improved I2C level shifter PCB compatible with the daisy chainable I2C splitter.

This I2C level shifter, designed following the Phillips application note, offers some improvements over the stripboard version I made earlier. The PCB uses the same footprint and header layout as the daisy chainable I2C splitter and hacked voltmeter (shown here).

Low voltage can be supplied on a fifth header pin or using a SOT-23 LDO voltage regulator. The ground pins are connected. The design files can all be found in the Github repo.
