This is an old revision of the document!
Currently a draft:
Low power design considerations
- Previous designs are pretty inefficient - lets take a look at why (the design choices are different for each hardware platform)
- Apple
- Cranberry
- Dragonfruit
- Guava?
- The assumption from before: we needed to either run things at 3.3v or 5v. Turns out we could run things at 2.8v - if we take a look at all of the modules, the one with the highest minimum voltage is the XBee at 2.8v. The atmega328p can technically run at a lower voltage.
- Need to figure out this situation: if we run the mcu at 2.8v, can we still use the regular usb-serial converter? I think the logic lines will be fine.
- XBee power states (sleep mode)
- Microcontroller sleep modes
- Other sensors
- How low can we go?
