Here is an action list to help with collaboration with Siddharth. Set status to “In Progress” when you start something so I don't take it. Put “Finished” when done. I can start with the pcb after the schematic is done. I will base it off of the nucleo shield file to make life easy.

Schematic/Pre-PCB Tasks

Status

Fix servo backfeed issue

Completed

Add seeeduino xiao to schematic

  • Make it have removable headers if possible?

  • Have debug pins for efs

Completed

Determine the correct connector for the gps and add to the schematic

Completed

Add wifi module to schematic (connector)

  • No longer adding this. Wifi will be part of the seeeduino to save pins.

Not Doing

Bonus tasks: Can be saved for next rev but good if time

Select and add neopixels

  • “Add diode for Neopixel supply voltage, drop 0.7V to meet data sheet supply voltage to logic voltage ratio”

Completed

Select barometer and add to schematic

  • Ask EFS for thoughts?

  • Just adding an I2C header, reasons mentioned above.

Completed

  • Display screen on board or external (TFT variant)

Completed

  • If possible usb port for debugging mavlink?

Not doing

PCB Tasks (Moreso reminders here)

  • support 30.5x30.5mm mounting pattern (EE standard)

Changes to existing board

...

  • Pick a new 5V buck that does not need an external LDO to reduce part count/footprint/cost.

  • Add on board antenna for the seeduino rather than replying on attaching one to it
