Ground station will be powered by external laptop batteries (through switch and 20V barrels).
Hardware requirements, power on, battery swap procedure explained in Electrical Notes.
Deliverables:
- Designed and tested housing plates
- Printed drawings of Pelican hole spacing and threading
- Printed drawings of component hole spacing and threading
Resolutions:
- Top plate mounting achieved despite limited space by using the fans to mount an additional plate for electronics only, stacking the pandas. This has the nice effect of putting the pandas next to the intake fan (lower fan, so you don't get hot air in your face).
- Weight reinforcement turned out to be unnecessary, but the additional plate underneath allowed for extra surfaces that more fully sealed the storage door, at the cost of making assembly a bit more annoying.
- There aren't really enough cables (or room) to justify a dedicated cable management channel, but there are a couple of positions for Velcro ties.
- Several more barrel outputs added to right side for future hardware (Ethernet switch, possibly)
