Design choices:

• Use a ATMEL MCU with at least 16kbyte RAM
• Use a DIL package for the MCU, so that it can be replaced in case of failure

The following list of components could be useful for the operation of the sensor node.

Provides power and lets us debug the output from the operating system and application program.
