Description: We took the Arduino Ethernet one step further and created an Arduino Compatible Wifi board! The board contains a WiFly RN-171 802.11b/g Serial Module from Roving Networks connected to the Atmega328P through a SC16IS750 SPI-to-UART chip.
The chip allows the RN-171 module to communicate with the atmega over the SPI bus instead of the USART. By keeping the USART bus free, the board is able to communicate with a PC using a standard USB to Serial Converter.
The Atmega328P is pre-flashed with the Arduino Pro Mini bootloader running at 5V and 16Mhz; which means it can be directly programmed with the Arduino IDE by just selecting Arduino Pro Mini 5v/16Mhz w/ Atmega328P during programming.
So what does all this do you ask? This board has the ability to serve up a website, or act as a client to get information from the world wide web! The possibilities are endless!
Important Note: The SD card on this board will not work unless the whole board is powered by 3.3V due to a lack of level shifters on the board. The boards come with the headers in the picture already soldered. If you need them without the headers, please contact us.
