Arduino compatible board with miniature WiFi ESP8266 module as main microcontroller. This is a ready-made solution for programming and using this module. The board has power converters and a UART-USB converter on board, which allows the board to be directly connected to a computer.
ESP8266 modules are quite attractive for smart home and home automation systems. The thing is that ESP8266 boards are not just modules for WiFi communication. The chip is essentially a microcontroller with its own SPI, UART, and GPIO ports, which means that the module can be used autonomously without Arduino and other boards with microcontrollers.
The module is equipped with a 32-bit Tensilica L106 ultra-low power microcontroller, clocked at 80 MHz and supporting 160 MHz. The microcontroller does not have on-chip user non-volatile memory. The program is executed from the external SPI Flash ROM by dynamically loading the required program sections into the instruction cache. Loading is done in hardware, transparent to the programmer. Supports up to 16 MB of external program memory. The ROM size may vary depending on the module version. The manufacturer in the documents does not indicate the exact amount of RAM on the die, but only an approximate estimate of the amount of RAM that will remain for the user after linking the API libraries - about 50 kB.
Previously, they had to be programmed using the Lua language, which created a barrier to mass use. Now it is possible to use the ESP8266 board in the Arduino IDE and write programs in the C-like language of this programming environment, as if you connected an arduino board (In detail). Most of the standard features have been ported and work fine. Some external libraries for arduino may not work.
The board has pin markings both for a typical Arduino board (Dxx, Ax) and for the esp8266 module (GPIOxx).
On the basis of this module, you can find a large variety of projects for creating and managing a "smart home". After all, it is very easy to turn a module into a web server with the ability to control external devices via GPIO pins, and control it from a computer, laptop, smartphone. It is worth mentioning that there are special app editors for Android and iOS, with the help of which it is easy to design an attractive interface for management and link it with our module.
