The below is a representation of the final board design. Don't forget to visit Tara's blog post for more details on how to connect the Arduino Nano to the T300 base.
- I ended up soldering the RTC package onto the main board to save space
- Everything was connected using Dupont angled male headers to reduce the height
- The Arduino Nano was also placed on female pin connectors
Both of these boards worked perfectly fine, but the v2 had a much slimmer profile which made it easier to fit in the enclosure. The RTC is not pictured on v2 as I had not yet (at the time) decided to hardwire it onto the board.
