To enable relay, host must toggle PIOA \nat least once every 1.6s, or the watchdog \nchip will disable the relay. After host stops\ntoggling WD, relay will be disabled in 1.6s.

Power can be 5-24V. Not sure how will the linear reg will handle\n24V so may need to swap that out later for something better.
