Also is this code valid for the 5V (direct link) or for the 3.3V (with voltage divider)?
from esp8266-vindriktning-particle-sensor.
If you connect the 5V pad to the 5V pin of the ESP8266 board, that's not merely 5V-tolerant, it's 5V required.
I understand the README to mean that the D1 is tolerant of 5V logic signals despite actually being a 3.3V logic mcu.
This project involves connecting the particle sensor to the 8266 via the IKEA PCB. The IKEA board and sensor run 5V logic, whereas per this retailer's spec sheet the D1 is 3.3V logic for all pins/ports.
I gather some have added a voltage divider to protect the D1, but many have not done so and (so far) found no ill effects.

@onshisan Ahh, that makes sense, thank you. Maybe the README should add the word "logic"?
