This serial modem brought to you by Switch Science allows you to interface an Arduino board with your iPhone or Android smartphone through the audio jack. Now you can integrate your smartphone into your next embedded project. Some software is required on the phone side, and of course there is an Arduino library.
Because the modem and supporting software exploits a connection originally intended for audio, some corruption of the serial data is to be expected from time to time. It’s recommended that you keep this in mind when writing your code. See the links below for more information on the b..
The MG2639 SparkFun Cellular Shield is a perfect addition to any Arduino project that requires connectivity when there’s no WiFi or Ethernet access nearby. The ZTE MG2639 module, which this shield is built around, supports SMS, TCP, UDP, and can even be used to make or receive phone calls! That means you can send and receive text messages, or use it to remotely connect your Arduino to the Internet. To top it off, it has an integrated GPS receiver, to help it from getting lost.
All the supporting circuitry is provided including translation from 2.8V of the module to a user selectable 3.3V or 5..
This is an evaluation board for the SM5100B GSM/GPRS module; everything you need to get started with the cellular module is included on this board. With FTDI’s FT232RL connected up to UART0 of the SM5100B you can send AT commands from a PC terminal straight to the module.
This board comes as shown in the picture with the 60-pin SM5100B mating connector, SIM card socket, SPX29302 3.8VDC high-current voltage regulator, FT232RL USB-to-UART, Mini-B USB connector, and more supporting circuitry. The SM5100B module is not included.
Note: If you don’t want to use your computer, or the USB to commu..
