Cons

• Unreliable connections

V1

Version one was created by Brandon Marcellus & Juan Silva early on in the start of the project after we had started some of the basic wiring of control and data collection.

Pros

• Power distribution

Cons

• Logic level shifter was not wired correctly
• Not enough IO ports were available for use
• SD Card module VCC pin was connected to 3.3V instead of 5V
