    I only had one day to play with this, but a few quick notes-- the mini board is tiny! And instead of using the lua stuff or even the arduinio IDE, I installed the Atom text editor onto my Ubuntu linux machine, then the platformio IDE on top of that. You can find a udev rules file in the link below that will ensure your user has access to mini nodeMCU as a USB device. (Instructions as to where to put it are in the link. You only need to put this file in place once.) Next, in the platformio IDE, I created a new project and selected the "d1_mini" board type (at first I accidentally chose the "nodemcuv2" type, but the gpio numbers were wrong. Trust me, "d1_mini" is the one you want). At that point, I could load the led blink "sketch", compile, and upload it. Got the flashing blue LED! Next, I was quickly able to get the WifiManage demo/library to upload and runwperfectly, which was cool cuz my computer found the esp8266 as an AP, enter my router's password, and it connected! I think had it run as a generic web server. (again, link below) Lots of fun stuff to try still, but this seems to work well so far and has been fun for a newcomer to arduino. And you don't really need anything except for a microUSB cable for your computer. Amazing. Links:

    These indeed use the lastest ESP-12F, with improved/more stable antenna and 4MB of Flash. They are not too large and allow for one free line on each side of a solderless breadboard. almost all ESP-12F pins are available (the bottom pins of the ESP-12F are not available) The reset and flash buttons are very useful. Though the 3.3v regulator consumes a bit more than expected. Great for prototyping. Some soldering is needed to attach the headers.

    I thought flashing/coding this chip would be a nightmare, but it has firmware preinstalled (no flashing required), example code is preloaded, and writing your own code is easy, there are some examples on the internet. Spent two nights investigating and I can now control relays and read temperature/humidity from a DHT11 I purchased for testing. Warning: it does not come soldered, which is a pain when testing, had to solder it.

    Отличный модуль. Хорошая доставка в Мытищи за две недели. Все отлично.

    These are the same as the Wemos D1 mini boards. There are loads of Arduino tools for these ESP-8266 boards. Ditch NodeMCu (it is crap anyway) and install ESP Easy, you will get a board with 4Mb, 80Mhz speed and it is way cheaper then an Arduino!

    I'm currently testing these small boards, I bought three of them, so far so good Nice little test web server included (defaults ssid DoitWiFi , pwd 12345678), but it runs on so I have to test it on a "stand alone" computer as my Gateway IP is the same.
