Do we have any preference on usb to serial chip (for ambiq module)?

  • Correct space between pins for RockBlock
  • More parallel battery-terminals
  • Use ambiq module
  • transistor for toggling GPS power @.*** https://github.com/zerblatt007 )
  • usb to serial for ambiq module

Have most of this in schematics form now..
We want the fuse and perhaps a regulator? image

zerblatt007 commented 1 week ago

Do we need something like this? image

zerblatt007 commented 1 week ago

My reference is this, but maybe not a good one? https://cdn.sparkfun.com/assets/5/5/1/6/3/RedBoard-Artemis-Nano.pdf

Can we use the pololu regulator that we already have on? We know it works with the modem, and it takes a range from about 2.5V to 11.5V?

Yes, of course.. It is set for 3.3V?

gauteh commented 1 week ago

Yes. It's not configurable. Always 3.3V.
