SimonXi- Increase the board width to let the board fit into bread board more easily
- Increase the tolerance for the outer half holes so that the machining process will not damage too much of the holes' copper coating
- AMS1117 has too high of the static current drawn and only able to regulate the power when the batter is above 3.3 V, so I am going to replace with the DCDC power IC from RPI Pico as it can handle both high and low input voltage
