ESP8266 - interesting platform for WiFi enabled projects

This small board can act as WiFi module for Arduino (or other µc - Teensy, Netduino, etc) or as standalone microcontroller. With RISC processor running at 80 MHz and with 1MB Flash You can do lot interesting projects. It has 2 GPIO pins to interact with other modules (OneWire).

ESP8266-01S technical details

  • 2 GPIO ports, each PWM capable
  • RISC processor 80MHz
  • power supply 3.3V
  • logic levels 3.3V

To program ESP You will need :

Power supply During start and in some working modes ESP takes up to 220 mA of current. Not all USB/Serial converters will provide such current. In that case You will need some separate 3.3V source to power module. More on ESP8266 current consumption topic. TL;DR: module takes from 220 mA in 802.11b mode, through 130mA - 150 mA in n or g modes to single mA in power save modes.
