Onboard Storage
Biosensor data stream should be in a non-volitile manner on the data aggregator board attached to the body. Ideally, the biosensor array will stream data wirelessly to a smart phone or computer, but this should not be required to ensure operational flexibility. Therefore, a moderate amount of on board storage is required.
EEPROM
- Pro's:
- Cheaper than flash memory
- Simpler to interface & manage
- Drew believes but needs to research
- Con's:
- Much smaller size that flash memory
- Not removable
- Implementations:
