[...]
Pin D1 is used to read the power status from the reset pin: High is on, Low is off. Transistor Q1 is used for secure isolation between ESP8266 and motherboard.

Pin D2 is used to pull the power button low to generate a short or long press. Resistor R1 is used to minimize current when the IO pin is accidentally set to output.

it's written different than on the picture, which description is correct? the image or the text?

Hi @jnsw, Thanks for your feedback. The schematic and text in the README.md matches as follows:

image

  • Pin D1 is the power status (monitor) ESP input pin: It is used to monitor the motherboard power state. Arrow <- IN below the R1.
  • Pin D2 is an ESP output pin to control the power button. Arrow OUT -> below R2.

Does this answer your question?
