Higher version with additional PCB

Lower version without additional PCB

Base is same for both versions.

From c source to cloud with ESP8266

There are many steps from c source code to cloud data storage. Let’s start…

In this contribution I will describe how I started using Espressif ESP8266 with Eclipse and some other details how to store data in “usual” web server. I will not talk about the hardware too much. To follow the tutorial it is enough to have any ESP8266 module connected to serial port on PC either via USB/UART virtual cvom port or directly (rare these days). Two most common possibilities are either module with the USB/UART integrated on-board or separated USB/UART + ESP8266-xx module (usually on breadboard with some additional periphery):

Two most common types of dev.boards for ESP8266
