Hi team! Please try an include as much detail as you can for the requirements.

Requirement

Subteam / Contact

Reason

e.g. There must be active airflow from 40mm fans towards the Semtech transmitter modules, with at least 20mm clearance above the semtech modules

ee - Anni

Heatsinks will be placed on top of the semtech modules.

Active cooling must exist in order to maintain full-power output from the semtech modules.

e.g. There must be mounts for the SMA/RP-SMA side of a U.FL to SMA/RP-SMA adapter in the enclosure

ee - Anni

We will be using u.fl to SMA/RP-SMA pigtails, and we want securely mounted SMA/RP-SMA sides.

< link to pigtail >

e.g. The xt-30 power connector U_ must be exposed

e.g. There should be a solid top-face of the case

ee

Protection from top-down rain ingress.

 Notes:

Complete water-proofing is not the intention. The intent is to make it less likely for light rain/snow buildup to damage our system.

Board may be mounted “upside down” (i.e. hung from the top of the case).

Louvres may be used on sides / bottom of the case to help prevent water ingest while still allowing for airflow.

  • U2 and U6 (only the coax output in the top left corner, rest can be covered)

  • All connectors/pin headers (J1, J2, J3, J4, J5, J6, J7, P1, P2)

  • ESP32 reset button (S1)

  • Chip antennas on left/right edge of the board (AE1, AE2)

  • The big white status LED near the centre (D1)

ee - Farris

General ease of use.

  • Top side Gemini board must be accessible by removing a cover. Similar to RPi case

  • Access to header pins

    • programming

    • debugging

  • Access to debug probe points

  • Access to ESP32 reset button

  • Connectors must be directly accessible. Plug and unplug without needing to open anything

    • J1 5V POWER

    • J3 USB FLASH/DEBUG

    • J5 TX16 CONNECTOR

efs - Derek

  • Ease of use

    • switch dead batteries

    • update firmware

    • switch EP1/2 device

  • Fans can be easily connected with the fan header pins P1/2

    • Image of RPi case fan installation above is a good example

    • Pls no wire surgery with pliers

efs - Derek

  • Ease of use

  • Antenna access to radio chips mounted at U2 and U6

    • U.FL to SMA adapter can be inserted into the case from the outside

    • The U.FL must be connectable to the radio chips, nothing immovable above the ports, no plier surgery

    • U.FL to SMA adapter will extend from the inside(U.FL side) to the outside(SMA side) of the case, leave hole(s) in wall of case

  • Ease of use

  • Big antennas, like the ones on tracking antenna, live outside the case

  • No labels
