@all,
Since @rickkas7 has published a new App Note on Watchdog Timers:
I thought it would be a good idea to adopt his design to replace the RTC and Watchdog elements of this design. This will simplify the board, align to Particle best practices and help improve the stability of the solution. I have respun the board and sent out for a few boards from OSHPark. Please take a look.
This implements the AB1805 watchdog without the supercap.
Hope you find this helpful.
