| Autopilot Module | | Updates: - Changed from Wago terminals to standard screw terminals for charge lines
- Reduced from 4 to 2 charge lines
- Did basic layout of charge lines
- Fixed address lines to go to inputs on Vocore
- Schematic is 90% complete
- Posted GPIO default state question to Vocore forum
TODOs: - Schematic
- Finish rest of backplane connector (GPIOs and LEDs)
- Clean up schematic
- Run ERC and make sure there are no design breaking errors
- Layout
- Placement of all components (really just one more charge line which is copying the one i've already done)
- Route all signal traces
- Route power traces/pours
- Run DRC and make sure there are no design breaking errors

Connector spec |
| Idea 1: "Horned connectors" going sideways - Positively locking
- Board-edge would look very neat
- Board-edge would take up too much space - we have 130mm width, 60mm per board is not enough margin
Idea 2: Back to proper backplane - Vertical connectors on modules pass through slots in the sled, connect to the backplane
- Sandwich the plastic sled by the PCBs
- Screwing everything to a common sled is positively locking
- Less wires means less integration hassle
- Maintain ability to use cables
- Need to specify connector offset on each module
- Radio module needs to send SMA connectors through the sled or out the short edge
- Need to carefully solder connectors so they're not canted
