Power Architecture
The drone will run a 12S power system.
...
All sensors shall be connected to the respective device owners listed in the hardware components section. There will also need to be a single uart connection between ZP ↔︎ Jetson, as well as multiple (at least 5) communication wires available between the PX5 and ZPHW.
Connector Standardization
Darwin Clark maybe this is something thath you can take a look at?Daniel Puratich To update via RFC: 2023-02-11 - Connector Clarifications
XT60 used for DC power.
XT90 used on batteries & solder pads for COTS ESC’s PDU’s
3.5mm female banana plugs on the ESC’s
3.5m male banana plugs on motor terminations?
...
For realism, we will have regular Nav lights on the dirty 5V or 12V rail, as well as a green PAX aboard light that is on a 12V or 5V relay controlled by ZP.
Custom Hardware Mounting Hole Specification
For general custom EE flight PCBAs going forward on ground station and aircraft we will follow this mechanical mounting hole specification:
M3 - Any PCBA with area exceeding 2500 mm^2
3.400mm hole diameter (0.1mm tolerance)
6.000mm annular ring diameter
M2 - Any PCBA with area exceeding 750mm^2 and less than 2500mm^2
2.400mm hole diameter (0.1mm tolerance)
4.200mm annular ring diameter
No Mounting Holes - Any PCBA with area less than 750mm^2
No mounting holes will be present on board of this size.
All Mounting Holes will follow:
Electrically not connected to the PCBA (frame is ideally floating potential)
Eight vias (plated drills) placed evenly in the annular ring (in whichever drill size is used on the board (so effectively left to EE in charge to decide on via size)) for mechanical stiffness.
Electrical components and electrically pads should be at least 1mm away from the annular ring to avoid damaging the PCBA when mechanically bolting the board.

Groundside Architecture
On the ground, there will be a primary “Ground Station” GS as well as the two tracking antennas “T_Telem” and “T_VRX”. GS Will be able to run unsupported (no power, no internet), for the competition for a minimum of 1 hour or from a standard wall outlet. Main batteries should be included within the GS Enclosure as the enlosure may be left outside overnight in inclement weather. All of GS should be weatherproofed, or be able to collapse into a weatherproofed box (it could be sitting in a mud/ or a puddle).
