After getting the Trinket, LCD, and INA219 to work on a bread board I drew up everything on Fritzing so I had a reference should anything go wrong whilst transferring onto a permanent proto-board.
I intentionally soldered on female pins so that:
1. All components could be easily replaced should they fail.
2. Components could be upgraded such as the LCD from size 16x2 to 20x4.
3. I could remove and use the components for other concurrent projects to save money.
