Temperature management of the cubesat airframe and avionics implies a requirement to have an ability to monitor temperature during development, testing and possibly flight.
The system controller board appears the likely candidate to add a temperature measurement IC which could monitor RTDs or Theromocouples (Type K or Type E (vacuum)? TBD).
- The system controller board has the capacity to react to temperature events.
- There is an open SPI connection on the ATMEGA128L on the current design.
- There is space available on the board layout.
Here is an example IC for reference:
