  • Battery backed RTC on the shield
  • Route VIN directly to an external interrupt pin (with some kind of voltage step/protection)
  • Route Sensor power enable pin
  • Make all peripherals off by default
  • DO NOT connect the apn switch to the WKP pin. Maybe connect usb voltage to wakeup pin.

  • potentially TPL5000 or some other external wakeup timer to WKP pin
  • make it more difficult to plug in particles offset on the headers
  • add temp sensor
  • low voltage interrupt? something to tell the particle to stay asleep that is more of a hardware trigger?
  • new sd card sockets
  • ye-sheng 60hz detector (likely for rev 5 or something)
  • lower cost imu?
