Introduction

• What

  • pi hat form factor

    • https://www.raspberrypi.com/documentation/computers/images/GPIO-Pinout-Diagram-2.png

    • sits on top of rpi for easy packaging, small enough to not require more support ideally

  • power supply for RPi 5

    • simple buck sized for the Pi

    • reverse polarity protection

    • input voltage range idk, but make it flexible for our drone

    • RPi 5 is a lot of power

      • 5 A for full peripherals, I think we only need 3 A tho

    • unusure on input voltage, need to think system level

  • JST GH connector 1:1 to pixhawk

    • either straight UART to pixhawk

    • could be CAN with a quick CAN to UART adapter as well

      • this isn’t rlly neccessary necessary if the pi is gonna be next to the pixhawk but is an option that may help for integration

      • would use common CAN circuit from ESC CAN Adapter

  • review other feature ideas with autonomy team

• Context

  • this convo

  • similar to how

    • Unified Video System makes the video system harness situation simplified

    • RFD900 JST adapter makes RFD have a 1:1 harness

    • this project will make RPi easier to use on drone and harder to mess up

• Why

  • Pushing reliability and integration improvements for https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2556133403/Big+Quad+2025?search_id=3f44a6d9-1ff9-4ffa-8138-9b5d38d1b7c1

    • locking connector

    reliable

    • 1:1

    connector

  When

  • low priority but could be pretty nice win on integration side!

    • harness between pix and rpi

• When

  • would like to start design in the summer to get this ready for next competition.
