Yun Shield Extension Board Compatible with Arduino Leonardo UNO Duemilanove Diecimila Mega<br /><br />Description:<br />Yun shield is one of the most powerful shields for Arduino Board. It is designed to solve the internet connectivity and storage issue for Arduino board.<br />Yun shield runs open source openWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later. Yun shield is the ideally choice for Arduino projects which require various internet connections and more storage.<br />Basically， Yun Shield + Leonardo equally to the official Arduino Yun， but Yun shield is more flexible because it can work with other Arduino board such as UNO， Duemilanove， Mega etc. And Yun shield uses external wifi antenna which provides stability and possibility for various environments.<br /><br />Main Features:<br />● Open source Linux (OpenWrt) inside.<br />● Low power consumption.<br />● Compatible with Arduino IDE 1.5.4 or later， user can program， debug or upload sketch to Arduino board via Arduino IDE.<br />● Managed by Web GUI， SSH via LAN or WiFi.<br />● Software upgradable via network.<br />● Built-in web server.<br />● Support internet connection via LAN port， WiFi or 3G dongle.<br />● Support USB flash to provide storage for Arduino projects.<br />● Failsafe design provides robustly system.<br />● Compatible with Arduino Leonardo， UNO， Duemilanove， Diecimila， Mega.<br /><br />    Specifications<br />General<br />	 Type: Expansion Board                                                  <br />                        Compatibility: Ardunio                                                	<br />Weight and Size<br />	 Product Weight: 0.036 kg                                                  <br />                        Package Weight: 0.096 kg                                                  <br />                        Product Size(L x W x H): 9 x 5.3 x 2.3 cm / 3.54 x 2.08 x 0.90 inches                                                  <br />                        Package Size(L x W x H): 12 x 7 x 3 cm / 4.72 x 2.75 x 1.18 inches                                                	<br />Package Contents<br />	 Package Contents: 1 x Yun Shield Extension Board， 1 x External Antenna                                                	<br /><br /><br /><br />                                                                                            <br />
