  • 3G Shield
    3G Shield Description: 3G Shield is an expansion board based on the SIM5216E Module, and SIM5215 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. 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 widel..
  • ESP8266 WiFi Module
    DESCRIPTION- This interesting module is a lot of fun for hobbyists and students who are interested in experimenting with the ESP8266 WiFi chipset. We bought a bunch of these modules, updated the firmware to the much-easier-to-use v0.924 and wrote some Arduino code to grab a webpage. We do not have a detailed tutorial at this time, this chipset/module is for the curious and adventurous! There's tons of details and experiementation over at This module is very low cost, but very simple. It doesn't support SSL, or communcation over SPI - just UART!  It doesn't have 5V to 3V logic level shifting so you'll probably want to pick up a logic level shifter, it also doesn't have a regulator on board and it can use big spikes of 300mA or ..
