Microduino GPRS/GSM

Microduino GPRS/GSM module plug in the SIM card and use some simple instructions to make Microduino core board connected to the Internet, and then send, receive text messages.

==Features==
*ESD protection；
*Uses USB powered or lithium battery solution；
*Supports automatic baud rate detection；
*Sends AT command and date via serial；
*Small, cheap, stackable, opened platfrom;
*Open source hardware circuit design, compatible with the Arduino IDE development environment for programming;
*Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly.
*2.54 pitch row female connector for easy integration into breadboard.

==Specifications==

Uses SIM800L module to support four bands GSM/GPRS, working band is：GSM850、EGSM900、DCS1800 and PCS1900MHz.

*Electrical characteristics
**Working voltage：3.4V ~4.4V；
**Under Sleep mode, current consumption is 0.7 mA

*GPRS data
**GPRS data transfer up to 85.6 kbps;；
**Build-in TCP/IP protocol；
**Encoding format：CS-1, CS-2, CS-3 and CS-4；
**Support Unstructured Supplementary Service Data (USSD)

*Serial debug
**Supports standard full-function serial, and transmission rate from 1200bps to 115200bps;；
**Supports GSM 07.10 protocol serial multiplexing function；

==Document==
*Eagle PCB： '''[[File:Microduino-GSM.zip]]'''
* Microduino-GSM module SIM800L：'''[[File:SIM800L.pdf]]'''
*SIM card base：'''[[File:SIM800L.pdf]]'''

==Development==
You can use GSM library to test, '''[[File:GSM.zip]]'''
Note：This library only supports Microduino-core.

==Application==
Send the text message using library's example program.
===Prepare Work===
*Prepared hardware：Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery；
*Prepared software: GSM library, Arduino IDE (1.0.3 release and upper)；
*Uncompress the zip folder to libraries of Arduino IDE；
*Connect the Microduino FT232R and PC using USB cable to download program and serial monitor；
*USB data cable or lithium battery to power Microduino GSM module and press the power button to make Microduino GSM boot, about maintaining 4S, turn on lights to indicate a successful boot.

===Debug===
*Open the example program SendSMS from examples folder；
*After compiled, select the board "Microduino Core (Atmega328P@16M,5V)", download directly；
**Opne the serial monitor, set the baud rate, and set to the line and press enter, will print "SMS Messages Sender";
**Input is completed, press enter, it will prompt you to input the sent content,
**Input is completed, press enter, you can see the text message sending progress. After completed, displays "COMPLETE!".
