  • seeduino xiao

    • main proccessor EFS is already devving around

    • needs to have access to pins for EFS debugging w/ logic analyzer

  • gps connector for external gps

    • contains compass as well

    • Neo M9N or M9P (see arch doc for link)

    • same as we use on the drone

    • this device has the CMOS battery inside of it

  • wifi module on the board or external, EE designer choice

  • barometer on the board

    • Doing it offboard since efs doesn’t really need it right now.

  • a few neopixels on the board

  • low battery indicator (need to have input voltage sense) → done already?

  • power supplies support 6S 5S 4S and 3S battery input

  • maximize mechanical packaging benefits

    • support 30.5x30.5mm mounting pattern

  • just do connectors to sensors instead of on the same pcba

  • sd card on board for logging → done already? Not in this rev for the sake of pin space

  • Display screen on board or external (TFT variant)

  • support 1:1 harnesses for all external modules

  • JST connectors for all off board stuff

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

  • If possible usb port for debugging mavlink? - Not mandatory

• Why

  • improve functionality for ease of development and connectivity

  • integrated in one thing for flight tests, easy to verify it looks good

  • Justified in Tracking Antenna Long Term Vision & 2024-06-01 EFS Director Sync

• Who

  • Ryan Scomazzon

• When

  • For Tracking Ant M3

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.
