I have a simple sensor done with a node-mcu (esp-12) that uses deep sleep and wakes up in the normal way, via the pulse from gpio-16.
I'd like to use the esp-01s module instead, the problem, of course is that gpio-16 pin is not available. In the particular model I have, there's even some small SMD components right in front of the gpio-16 pin, so, soldering a small wire between this pin and the reset pin is even more difficult.
My question is if it is possible to use an external device like this one http://www.ebay.com/itm/5PCS-Multifunction-Delay-Trigger-ChipTiming-Module-Timer-IC-Timing-2s-1000h-/311514571224 to do the hard work. Is there a "recommend" device ?
