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 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
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
1:1 harness between pix and rpi
When
would like to start design in the summer to get this ready for next competition.
