Resources and Going Further

Here are some resources related to the LLC and level-shifting in general:

• Schematic (PDF)
• Eagle Files (ZIP)
• • Philips AN97055 (PDF) -- An awesome application note covering bi-directional level shifting circuits.
• GitHub Repo
• SFE Product Showcase

If you're looking for a place to use the LLC, these tutorials might spark some ideas:

• Using the Arduino Pro Mini 3.3V -- If you want to stick with Arduino, and want to use 3.3V sensors, consider using an Arduino that runs at 3.3V. That way you won't even need to bother with an LLC!
