Hardware revision request: Improved power efficiency #1

Closed adamgarbo closed 2 years ago

adamgarbo commented 2 years ago

Hi @edspark,

I'm a big fan of MicroMod products and use them extensively in my research.

Unfortunately, one of the major drawbacks with many of the MicroMod products has been poor power efficiency (e.g., https://github.com/sparkfun/MicroMod_Data_Logging_Carrier/issues/3, https://github.com/sparkfun/MicroMod_Artemis_Processor/issues/5)

The new Main Board are exciting products. However, it would have really been nice if some of the design improvements identified in previous MicroMod products were addressed in these new designs. For example: adding a jumper pad added to the voltage divider (i.e., https://github.com/sparkfun/MicroMod_Data_Logging_Carrier/issues/1), or adding a P-MOSFET or extra regulator to control power to the microSD card.

Low-power data logging is an extremely desirable feature for end-users. While I don't anticipate a hardware revision of the Main Boards, my hope is that low-power operation can be given more consideration in future MicroMod designs.

Cheers, Adam

These are both excellent suggestions. I've added them to my notes for future revisions, thank you @adamgarbo.
