TODO List

The following changes should be made before fabricating any new MasonBot PCBs (as of 9/12/2017):

1. Pin 1 of 74xx245 is at VCC, needs to be connected to GND.

2. IR sensors connector needs to be mounted on reverse side of what is currently indicated.

3. ISP connector is on the wrong side.

4. ISP connector needs to be re-positioned to follow the Arduino standards.

5. Motor connectors need to be moved (too close to IR connector).

6. Motor connectors need to be on reverse side.

7. Extend pads on DRV8837 footprint.

8. Add vias for DRV8837 footprint heatsink pad.

9. Add mounting holes to PCB design.

10. DASL logo.

11. Power connector mounting hole adjustment, currently too close to pins.

12. Power switch mounting holes (OSHPark cannot do plated mill).

13. Add a reset/user button near the side of robot facing outward.

14. Find a new motor driver that has large pins (subjective).

15. Fix unconnected trace (<insert here>).

16. Move Wi-Fi module fully on-board and clear ground plane underneath antenna.

17. Move power switch inward (do not let switch extend past PCB).

18. Protection diodes for Wi-Fi module output pins.

19. Improve PCBs thermals for copper pour.

20. Numbered Arduino header pins.
