WeMos D1 ESP-Wroom-02 Mother Board ESP8266 - where is reset pin for deep-sleep This item was bought for battery use with deep sleep purposes. For doing so in ESP8266 reset pin must be connected to Gnd pin in order to wake up. This board lacks a reset on- board pin.
Since spec states it has a such capabilities - I wonder if someone has succeeded with putting it to sleep ( and wake it back on ).
PS - I know that on-chip gpio16 can be soldered to on-chip gnd - I'm hoping there is a more elegant, not soldering invloved, solution.
