The NodeMCU is gate tool for WiFi development, but it has some issues. The biggest issue for us at Institute Irans was the power consumption problem. Thanks to the open-source nature of the NodeMCU project we were able to improve the schematics and save a bit more power. Now the Irnas-NodeMCU is the great tool even if you want to power it up from the battery.
For further details please check the PDF schematics of the board. All issues with the latest release can be found in the Issue section of the repository.

Latest release: v0.1
Development kit for ESP8266.
It will make ESP8266 more easy. With a micro USB cable, you can connect NodeMCU devkit to your laptop and flash it without any trouble, just like Arduino.
It is an open hardware, with ESP-12-E core [32Mbits(4MBytes) flash version].
There are several ways to flash youre Irnas-NodeMCU the first one is using nodemcu-flasher and the second one is using arduino:
UPDATE New nodemcu-flasher is released. Bug fixed. please use latest software and re-flash. Enjoy. https://github.com/nodemcu/nodemcu-flasher
It is designed by Altium Designer, and fully open–source. Now everyone can make their own NODEMCU.
