How do you connect the reset wire on the dual watchdog to on the newer version of the USB PowerControl so it will properly trigger (turn-off-power) the low-power cycle (eventually turning power back on when the batteries recharge?).
According to the articles and diagrams you are supposed to connect the DOG1_ARDUINORESET to Cout (TP3) on the USB PowerControl and I can't find TP3 / Cout.
If you look at the pin locations diagram in the USB PowerControl specification, you will see the TP3 test pad marked. This is the COut / TP3 signal mentioned in the specification. It is also clearly marked on the board itself. Since it is in an image, a keyword search will not find it.
That is the signal you connect to the DOG1_ARDUINORESET (poorly named) signal on the WatchDog board.
