tl;dr

  • Discussed rough timeline for the fall, whether a faculty design review would happen for Pyxida 6.1, and reviewed some minor design changes for Pyxida 6.1

To Do:

CCB in 3 weeks

No external design review

External design review for the new flight computer, focus on getting faculty,

Software leads

Altium - get a licence.

50 Ohm terminators

Design Review Notes (Pyxida 6.1):

Changes to be made (Shreeyam):

    • Change barometer from BMP280 to MS5607
    • Change through hole SMA connectors to SMD inline SMA connectors
      • Better electrically, more mechanically robust, doesn’t interfere with programmer board
    • Fix the buzzer footprint (slight footprint error would prevent it from seating correctly)
    • L601 should have value 8.2nH, not 10nH

Things to Review (with Dennis):

    • TPS63001--100R resistor fix
      • is this the correct value we needed to get the converter working correctly?
    • BGS12PL6
      • Is this an appropriate RF switch for the application?
      • Are the components for this device chosen correctly?
    • Review why pins 11/12 are shorted on the CC1190 (LNA output and PA input)

Other/Misc:

    • Buy both versions of the 40MHz crystal for the CC1200 (like the original part and the new part Dennis suggested)
  • No labels
