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 4MB Flash You can do lot interesting projects. It has 9 GPIO pins to interact with other modules (OneWire, I2C, SPI).

ESP8266-07s technical details

• 9 GPIO ports, each PWM capable
• RISC processor 80MHz
• power supply 3.3V (3.6V max)
• logic levels 3.3V
• IPX antenna connector
• 4 MB of flash

To program ESP You will need FTDI friend or USB/Serial converter. FTDI cable 3 V will work only if You provide other power source, FTDI cable, even 3V version has 5V at it’s power line.

W also carry adapter, which has all ESP GPIO in 2.54 raster - You can plug this adapter directly into breadboard or connect standard F-M cables.
