Geekcreit® Wireless NodeMcu Lua CH340G V3 based ESP8266 WIFI Internet of Things IOT Development Module

Hello, is this NodeMcu ESP8266 ESP-12F or ESP-12E?

Can it go in deepsleep? Thank you L. S.

Hello. Why can't I install in arduino IDE ESP 8266. My installation doesn't work.Thanks for help

Are the data pins 3.3v or 5v tolerant? Clearly the board accepts 5v, and there is a voltage regulator to drop the supplied voltage to 3.3v - my understanding is that the ESP8266 is only 3.3v tolerant - so if you supply 5v to VIN do the data pins only provide 3.3v?Can you interface 5v I2C modules to this device, or only 3.3v I2C modules?

Does this board support deep sleep?

what is max voltage i can supply to V IN

How much memory is in the device? 512kB, 1MB, ... ?

Can I flash Arthur?

What driver should I use for Windows 10 PC connection the one I used for similar ESP8266 boards appears not to work

Cuánto cuesta: 2,***** o 5,*****? No entiendo que anuncien un precio y luego, en la ficha de producto se muestre otro :-(

Please can someone supply the distance between the two headers?

Mini or Micro USB the connection port?

will this board work with micropython?

I cannot boot nodemcu from Vin with voltage of 5 volts. The dev board only boot from USB. Can you please tell me how to power the unit without using the usb?

what are the dimensions of the holes and how far apart are they from each other ?

If I have two units for the internet, how does the internet tell the difference? I'm not into wi-fi, yet!

This is not the same as previous V3. Pin Rows are wider: 1.1in vs 0.9in and there was a LED on the board connected to D4 that doesn't seem to exist. The ESP8266 Wifi chip seems to run warmer than the previous V3 but is much cooler than the super hot V4. Is this really a V3 devkit?
