ESP8266 is 5V-tolerant after all? - Stack - Hackadayio

/29/2016Following up on the esp8266 talk this evening, here are the timings that I see. My esp8266 app starts 75ms after wakeup, WiFi is up 40ms later and deep sleep is requested at 320ms (from wakeup). The DSO shows power usage drops at around 550ms so it takes a long time (230ms) to enter deep sleep. Here is a DSO capture.

ESP8266 Pinout, Pin Configuration, Features, Example

It seems that the ESP8266 GPIO pins are 5V-tolerant after all, or at least protected from 5V input. ESP8266 is 5V-tolerant after all? What the datasheet clearly states is that above ABOVE 6. 0Volts the snapback will trigger and will shunt the input current so the voltage remains at 5. 8Volts similar to the way a zener keeps a constant

/10/2015ESP8266 - Operating voltage range and sleep current. Harvs Whilst the ESP8266 can stand the 4. 5V, the sleep current would be pretty high, so I stuck a regular 1n4001 diode in series with them and got about 4V. Not ideal, but not too bad, it will at least allow the batteries to discharge down to 1V each and still have a stable ESP.

/26/2018So I'm having a nightmare with this and hopefully someone can shed some light on it. . . now I THINK it's a current issue but I could be completely wrong. . . I'm trying to trigger an optocoupler with an ESP8266, with the optocoupler connected to the TX pin (GPIO1) of the ESP-01 module.

The ESP8266 requires 3. 3V power voltage and peaks at 500mA or so of current for small periods of time. You'll want to assume the ESP8266 can draw up to 250mA so budget accordingly. To make it easier to power, we put a high-current-capable 3. 3V voltage regulator on the board.
