| - | **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? | ||
