New product post - 3G shield

Hi, everyone, last week we updated four new products and we made a commitment in the next several days, we will continue to launch some other new ones. Currently the hot product - 3G shield will be presented before every Elecfreaks customer. 3G Shield is an expansion board based on the SIM5216E Module, and SIM5216 series module is a multi-frequency HSDPA / WCDMA / GSM / GPRS / EDGE module solution that supports HSDPA data transmission at a speed of no more than 3.6Mbps. Have a look. 3G Shield can directly replace the SIM5215, compatible with its Hardware and Software. The rich application features of 3G shield, such as supporting embedded LUA script, or TCP/ UDP/ FTP/ HTTP/ HTTPS/ SMTP/ POP3/ MMS and other software features, provide customers with more application flexibility, and greatly facilitate customers to do application integration. Meanwhile, its unique camera interface and video telephony features provide additional value to the monitoring program. The module can be widely used in meters, gateways, automotive telematics, asset tracking and security monitoring solutions.

3G Shield not only inherited the SIM5216E Module all application features, but also expanded many common interfaces, including two camera interfaces, a microphone and a headphone jack, USB port, SIM card interface, SD card interface, as well as the Arduino compatible interface. Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won't work.
