> 3 dayThis is essentially a PROTOTYPE of a particle.io knockoff. 1. The driver source doesnt support any Linux kernel beyond 2.6.25 - WHICH WAS RELEASED NEARLY TEN YEARS AGO 2. Quality control is non-existent. Device never powered up and the ESD packaging was ESD in appearance only. 3. The Dev Kit repository is just a mess created by developers that dont understand how source control works or why bundling source files in binary containers is an incredibly stupid idea I gave up before I bothered to find a number 4. There are so many other better products that offer more features and stability at the same price. Avoid HiLetgo like the plague.

> 3 dayIt didnt work. Sealed ESD package, no physical damage apparent. Apply power through the USB cable - get one blink of the blue LED on the ESP8266 microcontroller package. Then nothing. It didnt show up as a USB serial device. Tried a different USB cable - now it shows up as USB serial port, but I still cant talk to it. Nothing on the USB serial port (at any speed). Tried the esptool.py - nope. Tried other tools - nope. Gave up. Bought a two pack of boards from MakerFocus. Same physical board, except this one works. I suppose I should figure out if its worth it to return it as Im still waiting for money from Amazon to show up after a different purchase from another vendor.

> 3 dayLooks like I blew something on the USB port by drawing too much power. Was able to bypass by cutting the USB cable and wiring the 5v to the pins and works fine to power for xlights

Greater than one weekMine was not flashed with NodeMCU/Lua firmware so keep in mind if you expect to use ESPlorer out of the box. Roughly using the guide on Adafruits site for Arduino IDE and installing the 8266 Board Package in the Arduino board manager, I was up and running and tested with the ESP8266WiFi, OneWire and DallasTemperature libraries. Works great! Pretty cool to have 50kB SRAM available and 750kB of code space left over. This is not as straightforward as a regular arduino for beginners(logic is 3.3v not 5v and youll need a diagram to correlate the D1-D8 to GPIOxx pins) but if you need some more code and ram space, and dont need many GPIO pins (and it has only 1 analog pin) its great little board.

> 3 dayI ordered this board at $6.99 + $2 for shipping and handling (total of $8.99) on Jan 24th and received it on Jan 30th. I started to write a review and complain about the price hike to $14 and then I noticed that that it has become unavailable! I guess a lot of people are realizing now what ESP8266 12-e can do. I was going take one star off because I had to re-flash the board, but then I remembered this is par for the course for these boards. Other than that, the board is working as expected. When used with a breadboard, it leaves one connection point available on each side (which is not the case with LoLin V3 boards). After flashing the board, I tested both esplorer + LUA and Arduino IDE and they both worked fine but I had to re-flash the board after using Arduino IDE in order to use esplorer again. (But I had to do the same with a LoLin board as well.) If somebody knows how to go back and forth between the two without re-flashing the board, please let me know. IMO, unless Arduino moves to integrate Wi-Fi as this one does, and at a reasonable price, Arduino is dead as a viable IOT solution (except when your application needs the high number of GPIOs that Arduino provides). Next I am going to see if I can get all those devices that I got working with Arduino (LCD displays, sensors, etc.) to work with this board.
