custom CAN elrs comms

• Who

  • Unassigned?

  • Ideas

  • Likely Daniel and Anni if nobody wants this

  • Ishman is interested in doing the board?

  • Anni

    • Daniel Puratich can help with hardware design.

    • Anthony Luo can help with chip selection and architecture

    • Nathan Green can help with architecture

• Why

  • We want to use shorter antenna feed lines for ELRS and we have a big drone for https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2556133403/Big+Quad+2025?search_id=cadd3e16-591d-4512-820c-423e94a02153

  • lower loss feed lines require them to be short or heavier

  • want to stick with 2.4ghz elrs to get the bandwidth advantage as we’re streaming telemetry and rc over elrs.

• What

  • Possible Solutions

    • Use two RXes connect to pixhawk and add features to ardupilto and ELRS to support choosing the best one to use. one Rx on each side of the drone

    • Custom hardware to run SPI over a private CAN bus (so not datarate issues) between LR1121 boards which allows for normal ELRS firmware and ardupilot at the cost of more complex custom hardware
