Preparation for start of experiments with ESP8266

In this blog I want to share  my findings with Wifi module ESP8266. I have the feeling that this cheap module will become an important enabler for home IoT applications (prices of this chip family starts from 3€).
There are several chip models with different number of breakout pins available (ESP-01 ..ESP-12). For easy beginning I decided to start with a development board providing all interfaces for flashing firmware and application software as well some sensors (DHT-11 temperature, humidity)and actuators (relay, RGB-LED). The ESP8266 can be concidered as complete “system on chip” containing a microprocessor (80MHz), storage and Wifi communication.
I ordered 3 parts from ebay dealers in China:
– The standard ESP8266 ESP-01 module (2,80€)
– A develop board ESP-201 with module ESP-201 (with external antenna) for 13€
– USB-to-TTL adaptor

Before receiving the parts I checked for helpful blogs and wikis in the internet for reading technical information:

Due to this huge amount of information it is not necessary to describe more technical details. I want to focus to my findings in first experiments with ESP8266…
