Wifi Shield esp8266 for Arduino

描述

Based on the esp03, a new 2.4 GHz Wi-Fi module Standard 802.11 b/g/n Fully programmable, this shield provides to Arduino The WiFi connectivity and the support of memory on SD-card; offering the best quality/prezzocon consumption of electricity space ratio that makes it ideal for battery powered applications. The esp03 module is based on the chip esp8266 by espressif systems (http://espressif.com) This product contains, not only the stage RF, but also a fully programmable microcontroller and a register which are of I/O, SPI and the I² C bus of communication as a the this means That the component can from just deploy the communication in WiFi; in addition, the possibility to perform to chip a programme, allows the management of some pin (various GPIO, Bus) in order to achieve a system that can interface with external devices of various kinds or manage inputs and outputs. The shield has a jumper that allows you to select the pin to be used for the management of SD (by default, the library of Arduino uses the pin 4), a jumper that lets you select the D7 pin for the control of the operating mode of the module (in this case, via the D7 line of Arduino can be turned on and off the second need) module, a male strip connector with all the pin of the module esp8266 – 03 (useful for anyone who wants handle directly the module). The communication between the shield and Arduino is a standard serial and uses the two data lines, which may be conveyed to the serial TX and RX hardware, or on pin D8 and serial D9 (manageable with a software). Attention. The modulino Wi-Fi esp03 is for soldering.
